M4 build, boring, I know.

[Liam Porter]

Right, so I've got a spare G&P 8mm gearbox, G&P M120 motor and MadBull 363mm tightbore barrel.. they cost £200 for the three, and currently they're doing literally nothing other than gathering dust, which seems a waste.

So, I've decided to build an M4. I know they're common, but I've decided I want one that looks fairly standard, maybe a few small things that look different. But here's roughly what I'm planning, starting from the back to the front:

Stock: LE Stock with Li-Po in the stock tube, I already have the stock, but no stock tube. Would be grateful if someone can recommend me a stock tube that will fit a CA stock and a G&P body, that will also fit a Li-Po in it.

Rear sling mount on the back of the receiver.

Rear Sight: 600m flip up rear sight.

Receiver: Stuck on this one really. Would like to have an engraved receiver, so no white paint, but with official M4 markings, with "Burst" rather than "Auto". If anyone knows of one/where I can get one, it would be a great help. I've looked through all the receivers on Zero One, Fire Support and Red Wolf, but haven't found anything. It must be compatible with the G&P gearbox, metal, black and not have manufacturer's markings on it (e.g. Classic Army).

Pistol grip and trigger guard: Standard M4 pistol grip, like the one on my M16, so will get one the same. Same with trigger guard, like the basic M4/M16 ones.

Barrel: 14.5 inch barrel as I plan on getting the long version of the M203. If I do, I'll get the barrel mounted one, and then remove the bottom half of the RIS to mount it.

Front End: Will have standard M4 RIS, no free-float fancy stuff, simply because I already have RIS lying around somewhere and they're quite expensive to buy. Want a folding front sight, the one similar to the standard ones, but just folding rather than fixed triangle. Although I have no delta rings or gas tube, so brands that fit A&K and G&P would be good, haven't actually managed to find anywhere that sells just the gas tube on its own.

Standard M4 flash hider, and a quick detach silencer.

Will most likely fit a MOSFET to it, to then have burst fire and to protect Li-Pos. Any recommendations on a good one?

So, what I'm stuck on is:

- Front and rear delta rings - fit G&P receiver/barrel and A&K M4 RIS.

- M4 gas tube, fit a flip-up front sight, A&K RIS and G&P receiver.

- M4 receiver with engraved trademarks, "Burst" rather than "Auto".

Not too fussed on cost, as long as it's not too ridiculous, as this is a long-term build and I'm expecting it to be rather expensive.

If anyone has any suggestions on brands/ideas to change parts, then I'd be happy to hear them.

The brands I plan on using are G&P and ARES, as I have a G&P M16 and the externals are amazing, the ARES RIS on my M16 is also amazing and fits perfectly. Also read a lot of reviews of how good and realistic ARES's externals are.

Thanks.

Mainly I'd recommend you look at these sites (in order of preference):

http://www.wgcshop.com/wgc2008/main/

http://uncompany.com/

http://www.tokyo-model.com.hk/ecshop/index.php

http://shop.ehobbyasia.com/

If you can't find a G&P receiver set on there which fits your requirements... well... you should be able to, heh.

No idea what a rear delta ring is, you thinking of the castellated nut at the base of the buffer tube? Either way, G&P buffer tube will do the job you need, especially if you go with the G&P receivers.

You should be able to fairly easily find everything you need with just a bit of time on those sites; 90% of it at least on WGC I'd imagine, given the amount of stuff they stock.

 

[Liam Porter]

Thanks, I've never actually heard of any of those sites. I probably named it wrong, I mean the two rings that go infront of and behind the handguard that hold it on. I'm pretty sure I'll find one on there.

EDIT: Had a look at receivers on http://www.wgcshop.com/wgc2008/main/ and found a VFC one that has perfect markings, do you know if it's compatible with G&P? Also, what's the difference between the one with the longer bit out the back and the one with the shorter bit? If you know what I'm on about?

 

[BaggyPants]

Liam, I have a complete G&P standard M4A1/M16A2 pistol grip and a standard G&P steel M4A1 flash hider for sale in the classified ads.

 

[Liam Porter]

I'll have a look, but I don't have much money spare at the moment, and I've got a holiday to pay for coming soon, so this is an 'in the future' build idea.

Please say Malia next june 1st - 14th

If you want to have a look at ALL the options for pretty much EVERY different aspect of building an M4, try wgcshop.com - it's all listed under "accessories" as their "parts" section just contains internals, but they've even got some DYTAC M4 receivers with spartan helmets on...

 

[TheFull9]

No idea about VFC recievers myself I'm afraid, nearly bought one of their AEGs just last week but it didn't come off in the end. Personally I always say that the best bet is to just stick to the same brand of parts when putting together a build; admittedly on the odd rare occasion you might still encounter a tolerance issue, but the vast majority of the time everything will be all nice and compatible. If the product description says it's compatible it 'should' be obviously; I just have quite little faith in these things personally.

With regards the tangs on the lowers, the longer ones are aimed at mounting full stocks on M16s and similar ARs, whereas the short ones are more the standard and are optimised for mounting a regular buffer tube. You can always cut a long tang down though of course, 2 minutes with a dremel or hacksaw.

 

[Liam Porter]

Thanks, I've done a bit of searching for compatibility, and a VFC barrel and stock fit a G&P receiver, so that's looking hopeful, gotta check gearbox compatibility though

Would an M16 stock fit on a receiver with shorter tang?

 

[TheFull9]

As far as I know VFC do mostly build their stuff to the standard specs, and outer barrels and buffer tubes are pretty much universal throughout all AEG ARs.

Can't see why a full stock wouldn't go on a short length. Admittedly the last time I used a full stock and did any work on a gun with one was about 2007 on a CA but they should all just have a long screw that goes in to the back of your gearbox to secure everything together, exactly like a buffer tube... just a lot longer.

 

[Liam Porter]

Emailed WGC with my parts list asking if it's all compatible, especially the receiver, they replied saying it is.

Would a regular buffer tube fit on a receiver with a long tang, without me cutting it down?

Also, anyone know whether or not a Classic Army stock will fit a G&P buffer tube?

 

[TheFull9]

You'd need either the short tang, cut-down tang or an extended mounting screw to put on a buffer tube, no luck otherwise; screw wouldn't reach the back of the gearbox.

With the exception of RS 'commercial spec' the diameter of buffer tubes and adjustable stocks through airsoft and the mil-spec RS world is pretty much universal. You get tiny variations either way but the worst I've ever seen is a RS MOE on a G&P buffer and all that was was a bit tight, still went on there no worries. As a generalisation, airsoft stocks for buffer tubes are generally formed pretty loose, so if anything you'll probably end up needing a strip of tape on the inside to tack out some of the slop.

 

[Liam Porter]

Sorry to bump and old topic, but there's not point in me making a new one..

And I think I've built up a list of exactly what I'm going to get, unless someone points out a reason not to get a certain part.

Here's the list:

G&P M4A1 RAS Front Set, but replacing the fixed front sight with a King Arms Knights Type flip-up front sight. Rear sight being a G&P 600m flip-up.

VFC Metal M4 Receiver, with 'Burst' instead of 'Auto' engraved and a standard M4/M16 G&P pistol grip.

Stock will be a Classic Army LE stock (as I already have one lying around), hopefully fitting onto a G&P 5 position stock tube, with room for Li-Po battery.

Also adding a G&P M203 grenade launcher (long type) for good measure.

Does anyone know of any certain compatibility issues, apart from the following:

I know I'll need to cut down the tang at the back of the receiver to be able to fit the stock tube.

WGC have said that all the G&P parts listed will definitely fit onto the VFC receiver without complications.

Ones I'm not sure about are:

Will the stock fit the stock tube?

And will the King Arms front sight fit the G&P barrel and gas tube?

Thanks for any help.

 

[M_P]

Can't see any reason why the stock wouldn't fit. Obviously different brands build to slightly different specs so there may be a slight wobble- but that's to be expected anyway and won't really be a problem

Not 100% sure on the sight but I can't see any reason why it shouldn't

 

[Liam Porter]

What CKinnerly said about the stock/receiver is what I meant. That the long tangs are meant for fixed stocks and short ones are meant for retractable stocks.

Not too fussed about wobble as I can fix that with some nice tape .

Also what I was thinking about the sight, just wanted to make sure no-one knew for certain that it won't fit.

 

[Liam Porter]

Sorry to double post, but another question regarding G&P, VFC and King Arms.

I'll be ordering all these parts in the next couple of weeks as Amazon have been kind enough to give me a refund for my laptop .

Anyway, question is; does VFC use the same metal/colour as G&P in their M4s?

I ask because my G&P M4 is a different metal and colour to my mate's G&G. Mine's more of a grey whereas his is black.

I want all the colours to match, so the gun doesn't look too odd. I presume they'll be the same as VFC seem to have amazing externals as well as G&P.

But just to check, does anyone here own a VFC and a G&P M4/M16, if so, could you compare the colours and let me know how similar they are please?

Also, same with King Arms and G&P, I'm going to get a King Arms front sight, if anyone owns one of these and a G&P weapon, please compare the two colours.

Thanks a lot .

 

[Airsoft-Ed]

I actually think that mismatching colours can look really good to an extent.

The flash hider, RIS and the receiver of my L85 are all slightly different tones and I think it makes it look really good.

 

[Liam Porter]

Possibly.. I'll get on PMG and see what things look like . I love that website so much :L.

May not even get an M4 now, leaning towards an SR25 again :/

 

[M_P]

I texted a friend who has a g&p and a vfc , I'll let you know if he replies

 

[Liam Porter]

Excellent, thanks a lot!

Oh, and if he's had them apart, is the barrel thread on the receivers the same?

And are the two compatible external parts-wise?
