Update.... 

 

So, these next two have been on my search list for a very long time. 

 

So, first up 

L131A1.... (Glock 17 gen 4)

So this pistol eventually replaced the ageing L9 browning, with the gen 3 being in service with the sas before that!. 

 

Mine, is the very early fully traded and hard to find Stark Arms/VFC gen 4 glock. 

What makes this stand out over other brand glocks, is the markings!. So the later umarex/vfc , tm/guarder and GHK glocks, all come with the U.S glock markings. 

The Stark Arms comes with the correct European markings and German proof marks as found on the real L131A1. 

The only other brand close to this is the early WE fully traded glocks. Only issue with the WE glocks are, that the lower and upper look and marked a gen 4. But the recoil spring is still the slim Gen 3 type. 

 

I have also fitted real sights and lanyard adaptor, along with a replica QR code as also seen ok British glocks. 

Only thing left to do on mine is get the L131 and NSN details engraved on the lower. 

 

Top 2 pics are from the real L131

Last pic is mine. 

 

 

 

2nd one is 

L104A1 (HK69)

This was brought in for use in Northern Ireland to fire smoke and baton rounds. 

Then was later used in Iraq. 

And believe it still in use at the moment, as one pic was posted of it in use last year with a red dot as a rear sight. 

 

Mine is the hard to find original CAW HK69

When I got this, was sprayed all green. Took it back to normal, then weathered it. 

Also fitted real sights. 

In the process of getting some parts 3d printed to get it running again. 

Then looking at getting correct markings added. 

 

Top pic is of it in use. 

Bottom is mine. 

 

 

[2X Gen 4 glock 17]

Top is VFC 

Bottom is the early fully traded WE

 

Both have no mags, and have both sat for 2 years. 

Fps unknown. 

[Another big name gone]

Yeah it is a shame. I've seen lots of forums gonover the years. Some were still a hive of activity. 

UKAZ & zeroin were the other places to be. 

But UKAZ disappeared no warning. And zeroin how knows... 

Other than this forum, only leaves a few small ones. And the big American forum went last year too. 

 

For me it's a shame. As I always find the forums far easier to navigate and find threads. Without having to scroll past hundreds of posts. 

 

When fb started banning groups, I was really shocked that the forums didn't take off again. 

[Gun picture thread]

So managed to obtain an old CAW HK69. 

Was all painted and original sights were floppy. So added real front and rear sight. 

Removed to paint and weathered the metal. 

 

[LCT LC3 (G3A4)]

Thank you bud. 

Seems my rough price is near the money.. no pun intended haha. 

 

Will try and dig out a mount for it if I can find it. 

[LCT LC3 (G3A4)]

Looking for a rough idea on price for a lct G3A4

This is the non blowback version. 

This is completely stock internal, with a few marks external where sight mounts etc had been present. 

 

The fps is 400. So either needs down grading or locking to semi for DMR role. 

This is because ordered from abroad, and has come "as is" from Asia. 

 

Comes with 1 mag. 

But does not have the original box. 

 

Now these were around £450/500 new. 

So would 300/280 be the ball park? 

 

Cheers. 

[Gun picture thread]

LCT G3A4 

LCT G3KA4 (L100A1)

CA G3 SD

LCT HK53 (L101A2)

 

 

[British Forces weapons]

Latest arrival. With a massive thanks to a very good member on this forum. 

 

The L100A1 (G3KA4)

The real rifle was seen (and well pictured) in use with UKSF in Afghanistan. 

But was documented in use well before that. 

 

Mine is the LCT LC3K. 

It's set up in the configuration as seen in use in afghan. 

The flash hider had to be specially made by LCS Engineering. 

The grip pod has been stripped out, and turned into a battery box. This is due to the railed handguard leaving no room. 

It also features;

real

* handguard

* scope mount 

* rear sight. 

 

At the moment the dbal is busted. But will be replacing that when I can. 

 

Heres a warning to those looking at doing similar!!!!!.

The issue is that LCT isn't 1:1. 

So the real rail sits slightly too short. 

So trying to figure out how to get around that. 

 

Now just need to weather it a bit more. And may even add a very slight dusting of tan in the nooks and crannies. 

 

The other small thing is picked up a busted airsoft Claymore mine. 

The american designation is M18/M33. 

Still trying to find out the "L" designation is.

How did you have them set up at the time?

 

[Lambda/DCA GPMG]

If you head to the British Forces image thread. 

I made a massive post about it. 

It's a long, but hopefully good read. And can see every little detail that went into it. 

 

And it's this detail going into this gpmg project above.

[Lambda/DCA GPMG]

Here's one of the top loading mag trials....

 

 

[British Forces weapons]

Moving back to more of the H&K family. 

We've done the MP5'S, but now time for it's bigger brothers. 

 

First up is the L101A2 

 

The HK53 (L101A1) first saw service late 80s early 90s. 

Originally came with it's longer type flash hider, club style stock and a mix of either the early slim or later wider MP5 handguards. 

Most didn't have optics. But have seen a few sas pics of the C.W.S night sight fitted. 

 

Then towards later 90s, they all started having issues. Which was found to be the roller systems were getting worn. 

 

These were eventually upgraded and became the A2. 

These now sported the smaller G3 style flash hider, slim style MP5 stocks and surefire handguards. 

Most now featured a form of optics. 

Usual seen was the A.R.M.S MP5 mount with trijicon RX05 reflex sight. 

Others seen was the B&T rail with ACOG. 

 

Mine is a LCT version. 

Based off the ones seen with CP teams in Afghanistan. 

With surefire replica handguard, genuine A.R.M.S mount, replica trijicon and mag clamp and mag. 

 

Still need to source a slim type stock. But holding out till LCT release their MP5 in 2025. 

Only other work is to get the correct markings added. 

Left side had the HK markings. 

Right side featured the L designation and the NSN. 

However, I. Still trying to found out what the actual NSN is before I can get it engraved.

 

 

Next up is the G3A4. 

Now, mine is the LCT version. And was bought in the hope of getting it cut down to become the K version (L100A1) 

But LCT ended up releasing a K version, so mine ended up on the "for sale" pile for a while, as was told the G3A4 was never used. 

Till I did some research on intelligence groups in N.I. and was actually researching another weapon. Then got hold of some images and info showing that in fact, the G3A4 was infact used, but only in small numbers. 

So mine ended up back on the collection. 

Now meaning I've got to wait for funds to buy the LCT K version. 

 

At the moment I have done nothing to this at all. Just completely box standards, as that's all I saw. 

 

Sticking with the G3. 

 

I decided and had the opportunity to build the so called SBS MC-51SD 

 

Now, there is definitely proof that the MoD took delivery of variants of the MC51 in the early 90s for trials. 

The variants were;

* Normal MC51

* SD 

* Short K version. 

 

However!, The MC51 was never actually produced by H&K. 

They we're manufactured by FR Ordnance here in the UK. 

Which were found to be uncontrollable with the heavy amount of recoil. 

But as for seeing service, it's only been hearsay, despite it's delivery been documented.

The fact there has been no pictures of it, nor has it ever been denied or confirmed by any serving or ex serving personnel. 

Kinda leaves it as one of those mythical creatures of the weapons world. 

 

That been said. In terms of logic, would make sense the SD variant possibly been used. 

At the time of the SD variant been delivered. The SBS were sent to N.I to join one of the intelligence task forces (14 DET). Who at the time were known for using shortened or silenced weapons on ops. 

 

Whether it was or wasn't, I still think it looks a pretty weapon. 

 

So mine is both parts of a classic army sar 41 and a MP5 sd. 

The Mp5 front end had to be heavily modded. 

Slot for G3 charging handle had to be made longer. 

The section where it meets the body had to have bits either filled or cut off, same on the actual body too. 

Then the plastic handguard frame had to be dremelled at the back to fit over the g3 body. 

Extra holes added to the original mp5 screws to sit. 

 

As this is a "what if" kinda weapon to start with, I decided to add a 6p torch. 

The replica Z24 scope is on in the pics, but has actually been removed.

Also added blue unit colour and Butt number similarly place to other G3 variants seen in service. 

[British Forces weapons]

So after searching high and low for years, earlier this year I managed to get my hands on this S&T sterling. Formally known as the L2A3 SMG. 

 

But got alot of bits to do to get this looking reasonable. 

So have managed to source a genuine sling and rear cap (not fitted yet). 

I plan on having the rear end worked on to look more correct along with rear cap machined down slightly. 

 

The charging handle/bolt will be getting engraved along with an extra strip of metal at an angle to replicate how the real bolt looked. 

It also needs cutting down at the rear, as is way..... too long. 

I'm looking at getting a large spring welded and cut. This will replicate the real spring, while making way for the rear of the gearbox while still leaving working space for the battery. 

 

Engravings and stamps need adding to the top of the magwell. 

Then will be getting repainted as crap as I can. As real one, the paint would just flake off in areas. 

Some people will say that they had a weird wrinkled effect. And you do see these on deacts. But after doing some research, these were actually civilian/export versions sent out on MoD orders to commonwealth countries. I have been told a few did make they're way on to British armouries. But have no image proof, only hearsay on another forum. 

But there is a lot of controversy over the manufacturing of the sterling and the rights to produce. And was infact produced in 2 different factories. 

One was the original factory at the Sterling engineering plant in dagahnam.

Second was the Royal Small Arms Factory Fazakerley in Liverpool.

But will spare the history lesson for now. 

 

 

Next up, is a bit of a rarity. 

this is an original Deepfire M72 Law.

Th British designation is the L1A1 66mm. 

 

The real one was used for some years, till late 90s. 

Then when afghan kicked off, was brought back into service. But with a more modern and updated version of it. (L1A3). 

 

Mine requires a bit of work. Some of the screws holes need addressing/re taping. 

And the rubber has perished on the fire button. 

 

I have removed some of the older Deepfire stickers. And replaced with newer more accurate stickers.

Next up

Colt model 715 

Colt model 725

 

Model 715, later known as the Diemaco C7

This is more well known for use by the SAS during GW1. 

But the later variant is also used by path finders, paras and royal marines. 

What makes this stand out is the fact it has Colt export markings, an A1 style rear sight, yet an A2 brass deflector. Upper is refered to as the M16A1E1 upper.

Other thing is that it has an A2 style lower with full auto. The U.S versions originally only came with the burst option. 

My build uses a G&P M733 Upper along with a very old discontinued Guarder m16 civilian lower. As all other airsoft m16 lowers are either A1 types or marked Burst. 

For GBBR, VFC do the correct Type body to achieve this. But a pain like me if sticking to AEG. 

Has a steel barrel and front sight. Has a real m203 upper and quadrant sight. Still on the look out for the old school A2 metal trap door butt plate. 

 

Also Both my 715 and 725 bodies have had the serial numbers stamped and marked on upper and bolt the same as on a UK issued C7s, referenced here by Jonathan at royal armouries. 

 

 

C7

Heres a version of my later 715/C7 as issued to the paras and RM. 

 

 

Model 725, later known as Diemaco C8

This version is very close to the Colt 723, but the 725 was made by diemaco. 

Also has the same upper as the 715 (M16A1E1)

My build is a G&P M733 body, which at the moment is incorrect as its an A1 style lower with the auto markings, when it needs to be an A2 style lower same as the 715 above. So will stay as it is till I get a blank lower engraved. Also got a steel barrel & front sight. Real slim AR handguard, Old school metal stock and HAO Diemaco locking ring

[British Forces weapons]

L115A3

 

This is the ARES AW338 spring version.

It's all pretty much standard at the moment, needs some work internally.

 

Externally I managed to source the correct flash hider for this. The brand is calibre, and had to order from abroad. But never heard or seen them since.

I know ARES did do one similar for their Stryker range, but the dimensions made it look fatter than it should. I was also led to believe the AW338 barrel is slightly thinner than that of the stryker, leaving their flash hider too loose a fit.

 

I've added extra serial number stamps on the bolt and handle as is done on the real thing. 

 

Managed to source the correct Type scope mount, and a replica S&B scope. 

Then I've had a dovetail to picatinny scope mount 3D printed, correct to the real one. 

Now at this stage, it is just a prototype. And still working on the finer details. 

 

Other part 3D printed, is the L115A3 45° STIC NVG rail. This Is clipped into the front of the rifle as per the real thing. 

Both parts have been painted an aluminium colour. Then sprayed over with black. 

Worn back around the edges, giving the illusion it's metal. 

 

As I have based this off of L115s in Afghanistan. Most rifles seen were covered in tan SCAPA tape at the time, with some individuals adding some extra colour/camo to their rifles. Similar to those seen on the earlier issued L96 at the beginining of the OP herricks in afghan. 

 

Mine is a replication of that, covered in SCAPA, and the paint scheme similar to that of a family members. 

Also added ranging marks as also seen on sides of the rifles at the time.

Well now i feel like my whole life's been a lie. ☹️

It's fine. 

Trouble is with alot of embassy images and even task force black stuff. So many people have recreated it or done impressions of it. That when you do search for images, ends up flooded with airsoft or reenactment pics instead of real deal ones. 

And unless you know what exactly to look for, it can be very confusing. 

 

We've all fallen fowl of it at some point. 

So don't worry too much.

It catches a few people out. 

This photo is actually from a BBC documentary on the seige. 

 

Here's a pic of the same gun, different angle.

[Lambda/DCA GPMG]

It will be slightly proprietary, as its an internal magazine. Similar to the vfc m249, but with the choice to buy a jungle tin if you want an actual box mag. 

 

I just hope they get it right. 

As I have been involved in this from day one. 

Infact it's my GPMG that has been used for all the measurements and all my info I've gathered over the years for them to get it right. 

 

Yes there maybe teething problems to start. As theyre hoping to have the prototype finished soon, and a working video of it shooting in next few weeks. 

 

(And no, I'm not affiliated with Dave. But I was sort out to help by both him and lambda with this, as I built my own gpmg from scratch. Hence I know what's gone into this project.)

 

[British Forces weapons]

L108A1 MK1 MINIMI.

 

Mine is a take on the minimis used by the ill fated SAS team "Bravo two zero" during Gulf War 1

The pic below is their actual weapons that were captured!. 

 

The weapon system itself was just a standard Mk1 minimi. You may notice in the pics there is one difference!

it was fitted with a gpmg flash hider. 

Which was also adopted by the Australians on their minimi's. (Designation F89) 

The L108 was only ever really used by the SAS. It was some years later before the minimi would become issued among the regular army. But that was the PARA version which was later designated the L110A1/A2

 

However the L108 was, and believed still is held in stores. 

 

My L108 is an original TOP M249.

Has been upgraded externally with 

Guarder steel gas block & front sight, guarder steel upgrade body parts, guarder steel barrel/top cover block, g&p steel cocking lever, g&p steel bipod. 

Replica steel gpmg flash hider. 

I will eventually get round to doing internal, and convert the original gearbox over to a classic army one. 

Was then sprayed and weathered. 

 

L7A2 GENERAL PURPOSE MACHINE GUN 

WARNING.... EXTREMELY LONG READ!!!
I've tried to keep this as short as possible without losing too much needed info. An even deeper version will be done at a later stage, which will also focus on the early FN and newer HK versions. 

This is a complete custom build, made of full steel, and is currently 99.9% accurate to a real L7

I know that for some of you, who have seen some of this build before, we’re covering old ground - but please don’t run away just yet!
 
Now, with the final piece of my puzzle, an accurate custom made steel barrel arriving. I've decided it was time to sort it all out, and refresh the build for a more informative experience. And to help explain why the L7 isn't just another M240..... 

Also, having done so much research over the course of this project, I’d thought it was time to share some of what I’ve learned and hopefully shed some light on why the changes I’m making were necessary. I’d also like this post to be able to aid others in their builds, and to hopefully shine a light for those with a particular eye for detail upon the things that might otherwise be overlooked.

So, let’s begin.

The basis for this project was originally an Inokatsu’s M240B. However, over time, this changed, and I had to have a completely new body and barrel made due to the amount of differences. The old inokatsu bits ended up being used in exchanges of parts.

So as I got thinking about making a British variant, I did decide to do a bit of light reading (so I thought) - and I was completely astonished by just how much history surrounds the GPMG.

So, for the history lesson!

THE FN MAG 58

The first Fabrique Nationale d’Herstal (FN) MAG was designed in the early Fifties by a guy called Ernest Vervier. It combines the trigger mechanism and belt feed system from the WWII-era German Maschinengewehr 42 (MG42) with a more updated take on the gas-operated mechanism from the WWI-era American Browning Automatic Rifle (M1918 BAR). It was called the MAG 60-20, later the ‘MAG 58’; MAG being the acronym for "Mitrailleuse d'Appui Général’ or “Mitrailleuse á gaz”, French for ‘General Purpose Machine Gun’, and “58” denoting the year production commenced.

The 3 primary MAG variants were:
• MAG 60-20 Infantry version
• MAG 60-30 Fixed aircraft version with either left or right feed
• MAG 60-40 Coaxial version

Specifications:
• Calibre: 7.62x51mm NATO
• Action: Gas operated, open bolt
• Feed: NATO M13 ammunition belt or the non-disintegrating DM1
• Weight: 10.9kg (24Ib)
• Length: 1,232mm (48.5 inches)
• Rate of Fire: 625 - 900 rpm
• Muzzle Velocity: 838m/s (2,749ft/s)
• Range: 800m (2,625ft, light role) - 1,800m (5,905ft, sustained fire role/tripod mounted)

THE L7

The original British variant of the MAG 58 (technically the MAG 60-20 T3), the L7(A1), was brought into service in 1957 and produced by FN. Then in 1962, under license by FN, the Royal Small Arms Factory (RSAF) in Enfield Lock, took over production making further improvements and incorporated into the L7(A2) (MAG 60-20 T6). In 1984 the RSAF became Royal Ordnance Plc., which four years later was bought out by BAE Systems, resulting shortly thereafter in the closure of the original site. After that, it fell to several sub-contractors, notably Manroy Engineering (now FN UK), to oversee both the production of spare parts, and general refurbishment of the GPMGs until mid-2008.

In late 2008, Heckler & Koch were given the contract to produce all spare parts and accessories, having had the task of producing new barrels for the gun since 2003. In 2011 HK won an additional three year contract for a mid-life improvement program (MLI). In 2008-09 the MoD solicited tenders for manufacture and support of the GPMG; by this point the original design copyright owned by Fabrique Nationale d’Herstal had expired. The three main respondents were HK, FN, and Manroy. The tender required the entrants to submit guns for testing, with HK’s version being the most publicised. Finally, after years of testing in the laboratory, training and in the field, in late 2014 the MoD announced that HK had won the contract to produce the L7s and their spares for the next few years.

The L7 GPMG, nicknamed “the General” or “the Gimpy” (pronounced ‘Jimpy’), has seen every British military engagement since entering service, including action in Aden, Borneo, Rhodesia, Northern Ireland, Oman, Falklands, Bosnia, Kosovo, Sierra Leone, Afghanistan, and Iraq.

THE MAG 58 WORLDWIDE

Over 200,000 examples of the MAG series and other variants have been used by more than 80 other countries over a similar period under different designations.

For example:
• Austria - 7.62mm MG MAG/Pz
• Argentina - 7.62 ametralladora Tipo 20-60 MAG
• Brazil - M971
• Canada - C6
• India 7.62 2A1
• Indonesia - SPM2
• Republic of China - CQ 7.62x51
• Sweden - KSP 58
• Taiwan - Type 74

THE M240

America did eventually jump onto the bandwagon, but relatively late and not until it had designed its own version of the MAG series. Known as the M240, it was put in service in 1977 and was used only as a co-axial variant fitted to armoured vehicles. An infantry variant - the M240G - wasn't introduced until 1991 by the USMC as a replacement for the dated and unreliable M60. The US Army adopted the weapon in 1995 as the M240E4, later the M240B.  As in British service, several variants were to follow, including the M240C, M240D (E1), M240H (E5) and M240L, which is a new lightweight variant. Compared to the L7 the M240 infantry variant has only seen a few engagements mainly, Somalia, Kosovo, Afghanistan and Iraq (1991 and 2003).

THE PARTS

Like myself at first, many people don't realise just how different the L7A2 and M240 are, despite being the machinegun equivalent of siblings. After extensive research and months spent studying plans, photos and parts lists, I was left with a list almost an A4 page long of parts and work that would be needed to turn my M240 into an L7A2. Over the course of a few years, I gradually acquired all the parts necessary to complete the build. 

They were:

• Inokatsu original style replica flash hider
• Barrel washer
• Foresight & Foresight block (early type)
• Sling swivel
• Bipod with height adjuster
• Bipod retaining latch
• Gas block & gas plug replica
• Gas regulator
• Top cover
• Top cover plunger
• Top retaining bolt and castle nut
• Carry handle assembly
• Barrel release catch
• Cocking lever and knob
• Feed tray
• Ejection port cover
• Trigger Group retaining pin
• Rear sight aperture and slide
• Trigger grips
• C2 sight side mount
• Stock
• 50rd belt tin
• Sling

Later came things like my tripod, carry cases and all the other ancillary parts associated with the gpmg. 

As the build started to unfold, I took the opportunity to actually show you some of the major and minor differences between the L7 and the M240 parts, to help explain why I needed to change or alter so many of them.

Now, not just the parts, but even the body differences are quite drastic. 
• Rear sights
(M240 straight, L7 curved with finger grooves)

• Reinforcement for stock on side plates
(M240 bigger gaps, L7 more Reinforced)

• Cocking lever support bar
(M240 grooved, L7 more reinforced)

• Front trunnion
(M240 has a small ridge, L7 rounded)

• Gas tube
(M240 has large rear section, L7 slimmer rear and 2 vent holes. Also to note the L7 variant has grooves both sides to allow for an ambidextrous mounting of sling swivel. M240 will only sit on the left side)

• Barrel
(M240 is smooth behind Gas block, L7 has 2 grooves that allow for a better seating on Gas tube)

 

MARKINGS

The top row speaks for itself; the next row is the first important bit. 
The first two letters denote the country then factory; "BL" for ‘Belgium Liège’ (meaning the gun was made by FN), "UE" for ‘UK Enfield’ (meaning the gun was made by RSAF), Additionally, "HK"  for ‘Heckler & Koch’ along with their test batches will be engraved on all future GPMGs.

The next two numbers denote the year of manufacture, e.g. 75 for 1975. The possible combinations are 57-73 (BL), 62-88 (UE) and 08-11 12-present (HK).

The "A" prefix is a batch number and was just added to the sequential sequence to allow the 4 digit serial number to remain (e.g. A0001-A9999, then rolling over to B0001 if the production for an individual year exceeded 9999 guns). Then next the four numbers are the last four digits of the weapon’s serial number. Newer Heckler & Koch made examples have 6 digits followed by three proof marks.

The bottom row of numbers is the NSN (NATO Stock Number) for the weapon. The NSN is a 13-digit code used to identify more or less everything purchased by NATO forces. Individual components and whole weapons are listed (for example, the GPMGs carry handle alone consists of six individually-NSN numbered parts; the entire assembly is also listed as a single NSN). The weapons themselves are listed whole:

L7A2 - C1/1005-13-103-2524
L85A2 - C1/1005-99-250-9030
L119A1 - C1/1005-21-920-6546

BARREL MARKINGS

Early Barrels ( before HK) were stamped with a “L” designation along with the weapon’s serial number, which should be within 6” of the chamber on the right side using a 5-6mm (⅛”) stamp. This would normally be the weapon’s full serial (‘UE84 A2912’) and barrel calibre.

So the infantry barrel was designated L1A2.

My original barrel has been done, just need to get the new steel one done. 

The reason why barrels are normally stamped with the serial number is because each barrel is paired to a specific parent gun, and not supposed to be used with other guns. This is because of cartridge headspacing (CHS) matching between the barrel and body. So over time the barrel locking thread on the body wears, and to counter this various size locking nuts with different thread thicknesses are in use.
On the locking nut itself, there are some serrations that the barrel locking latch will use to keep the barrel from coming free, and these cause the latch to click repeatedly as the barrel is locked home. The number of clicks is important - the minimum is three and maximum is 7 - as it demonstrates whether the barrel nut is too worn. If the latch clicks fewer than three times, the barrel will not be held or locked sufficiently. If it clicks more than 7 times, then the thread on the gun has become worn and the locking nut must be changed for the barrel to stay positioned correctly. Because one gun may have to use barrel nut size 2, it may fit perfect on that gun, but it will possibly be too tight or too loose to fit onto another gun; hence, the pairing arrangement.

PAINTING

Early gpmgs were painted with a paint called  Suncorite 259. This was then changed in mid 2000s, having been phased out under new EU environmental regulations. All contractors - the likes of Manroy and HK - are now free to use their own firearm coatings, so long as they meet the standard, which in the UK is called ‘DEF STAN 80-56’. Mine was sprayed with what’s called ‘Small Arms Black’. However, I have also sprayed parts with Halfords satin black and can tell you there's not that much of a difference. 

BALANCING MARK

On British GPMGs they have a white line placed towards the rear right side of the weapon, called a balancing mark. The white line corresponds to the position the cocking handle should be in when ‘balancing’ the weapon. It acts as a visual guide to show where the working parts make contact with the second sear (the former being the safety sear). The safety sear was put in on later models to stop what’s known as a ‘runaway gun’, a condition where the bolt doesn’t engage the sear and the gun will fire uncontrollably without trigger input until the ammunition is exhausted, you have a stoppage, or bits of the gun begin to melt.

These would be placed from new or fresh refurb, when the weapon was balanced with it’s parent barrel, and its spare barrels matched. The mark can vary in size with Tippex or a white paint pen. The line itself will always be placed directly above the last rivet.

UNIT MARKS/BUTT NUMBERS

These are basic armoury numbers for quick counting and easy identification, and are normally referred to as “Butt numbers”. These are most commonly found on feed covers & buttstocks. The numbers are there for ease of retrieving a particular weapon from the rack. For example, L7A2 BL69A073249 could be rack number 55. It’s easier, when looking at a rack of 100+ weapons, to just grab the one with the big 55 number on it, instead of having to go through each weapon to check for the serial number.

These would often just be written on with a paint pen, but is becoming more common to see them done with a label machine. 

Other number/marks will include:
Vehicle or unit call sign, e.g. "10B", "33A", "24C" with the exception of "11" and "22" in an armoured battalion.
The number plate if mounted on a vehicle, as has been seen on some wmiks in afghan. 
"Sf(followed by butt number)" if part of a Support fire role (with tripod)
Zap number; the individual soldier’s casualty identification number, this is the first 2 letters of the surname and the last four from their service number. For example, Davis 25015598 would be DA5598. Some people had this written on a bit of scapa/sniper tape, which was wrapped around the stock just in case in Afghanistan, but it was not standard procedure.

Units have also been known to paint colours on the top covers. This is sometimes done to identify a company or squadron within a regiment, battalion or battle group. Coloured patches are normally placed on the top cover, and although it’s not commonly done, it is more often seen on L85s & SUSATs

The usual main colours are red, green, blue or yellow. 

I've kept mine simple, and just added the number "13". 
Originally I had it marked with red to symbolise A COY 3 PARA in afghan 2008. But later removed it. 

Barrels 
Some times the carry handle is marked to determine if its the main, spare or even blank barrel. Some are even marked with the weapons serial or sf number. 

I've added the number "1" to mine to determine its the main barrel. 

GEARBOX AND FEED SYSTEM

Having devoted so much of this thread to the externals, it's time to show the beating heart of the beast. The gearbox was originally built up when I purchased the M240. Since then I’ve had to replace a few bits due to general wear and tear, but this is how the internals stand at present:
Guarder SP110 mainspring
Ultimate piston head (ventilated hexachrome aluminium)
Systema Area 1000 v.3 cylinder head
Systema Area 1000 Teflon cylinder
Systema Area 1000 oilless 6mm bushings
Systema Energy v.3 tappet plate
Systema v.2 flat gear set
Systema Jet AK nozzle
TM AK hop-up chamber parts
Madbull Blue hop-up rubber
TM EG1000 short-shaft motor
TM 509mm (M16-length) inner barrel

It currently chronographs at 337fps with Blaster 0.20g BB’s; consistency is excellent and the range is wicked on 0.20's, although trying to get it to fire individual shots is very hard as it’s either safe or cyclic! I've kept the standard barrel on this and not upgraded it for the simple reason that I want to use it how a support weapon should be used. With work I could have it DMR accurate, but I like to harass a whole barricade, not just one person.

The inside of the Inokatsu is a fairly typical AEG gearbox; what complicates the gun is - as usual for box-fed airsoft guns - the feed system. I had originally wanted to use a G&P M249 auto-winding box magazine. Unfortunately, after receiving a donated one I found that the mechanism itself was just too big to fit into the smaller 50rd ammunition tin fitted to my gun. I looked at other types of box and drum magazines, but nothing stood out until a forum member approached me with a spare Echo1 M240 box magazine for sale. Having received it, I promptly ripped it apart for the feed mechanism. Unhappy with the wiring I decided to strip the G&P box for parts too, and soon a Frankensteinian monster was in the making.

The chief reason for trying to marry the G&P’s electronics to the Echo1’s mechanics was my decision to power the gun with a 9.9v LiFe. The Echo1’s harness is made of extremely thin wire, and I’m worried that the stress of long bursts of fire may cause it to overheat. The G&P harness is heavier-duty, and also has a circuit board with an integrated transformer to vary the battery’s high voltage to the lower voltage required by the winding mechanism’s motor. Usefully, the circuit board also continues to wind the magazine for a few seconds after you release the trigger, ensuring there are BBs fed for the next burst. I cut and bent a metal plate to act as a makeshift reservoir, and cut a rectangle in the side of it to hold the LiFe.

I'm still looking for other ways to store the battery, so this isn’t necessarily final. I also tried to think of a way to hide the feed tube, but there wasn't enough room to do so; for the moment at least I've had to stick with the feed sticking out the bottom. The feed tube may have been too big but the wiring wasn’t, so that has now been hidden after making a cut out in both the body under the feed tray and on the edge of the ammo box lid. Bear in mind that this magazine is really only a prototype and still under development. I need to make sure things work reliably, and I would like to simplify the wiring at some point before I make something more permanent

 

 

Hope you've enjoyed this build and all the info that makes the L7 unique, and you haven't fallen asleep yet. 

Thank you for taking the time to read.

Now for the finished item... 

 

[British Forces weapons]

L129A1  sharpshooter.

 

The real rifle is a Lewis Machine & Tool (LMT) 7.62mm sharpshooter rifle. 

The British then gave it the designation L129A1. 

It features 

*LMT crane stock

*LMT rail panel

*LMT sling point

*LMT Ergo grip

*KAC flip up sights

*Harris bipod with A.R.M.S QD mount

*Surefire FH762K05 flash hider

*TDI arms FFGB2 folding grip

 

Most models came with the 

*Trijicon Acog 6x48 BAC .308 scope. 

But some others were also fitted with the

*Schmidt & Bender PMII 5-25x56 scope.

These were the main scope used on the L115A3 rifles. 

 

The airsoft one;

These are not your run of the mill production models. 

Both the flash hider and rail, are custom made replicas of the real thing. 

 

Mine is fitted with

*Clone KAC flip up sights. 

*Clone LMT panels

*Clone LMT Ergo grip. 

*Genuine LMT stock

*Genuine LMT sling mount & Rear plate

*Clone TDI arms grip

*Clone Harris bipod

*G&P bipod mount

 

The base rifle is a G&G SR25 E2 APU model. 

I've also added butt number with a white paint pen and also the British QR code to the magwell. This is where it is placed on the real rifle. 

There are a few things that needs doing to this. Mainly getting the correct trades done. A few other parts of the body changed. 

Then giving it a coat of FDE as per the real rifle. 

 

 

Next up is the 6X48 Acog. 

Mine is a 3D printed version. 

Lots of stuff has been done to this to make it as accurate as possible. 

A clone 4x acog was used as a donor internals. 

Whole thing was sprayed silver, then had several layers of black over the top. Then just weathered it back to look like it's really metal.

Also added the QR code, serial numbers and butt number to the top. 

 

 

[British Forces weapons]

Model 603. 

 

The model 603 is what later came to be called M16A1. 

The ones issued to UK forces was the Colt export version. 

These became the go to weapon for the SAS In many theatres for some time. 

 

The difference between this and other AR platforms in use, 

The 603 had a forward assist, aswell as a full fence side. Compared to the non forward assist AR's in use like the 604 (partial fence) and the early 602 used in borneo (slab side) 

They also did away with the duck bill flash hider for the standard A1 type and a phosphate bolt, where 604 and 602 were chrome plated bolts. 

 

Mine is a take on ones seen sprayed/taped during jungle warfare and the odd ones seen during the falklands. 

 

Only thing that is left to sort on this, is to get rid of the standard markings and get the Colt M16A1 export marking ls added. 

And for those looking for the extra little details. 

The 603s had their serial number crudely engrave on the left side l, inside the carry handle.
