Any standard AEG hop rubber should do. Maple Leaf are highly rated, and I have had good results with G&G green and TM black. Have a look on AK2M4.co.uk

Yep, here it is Grab a beverage and settle down for a long read!

There was a spreadsheet produced by someone on here that allowed you to plug in the numbers and it would give an estimate of the range attainable, it even took into account hop up (Magnus effect) It might have been @Adolfhamster? Heavier BBs carry their energy further and have a more pronounced hopup effect, with no increase in drag caused by air friction. I can see what some angry airsoft techs are saying that some builds work better with, say, 0.28g vs 0.36g ammo. Best bet is to get samples of ammo and give it a test! I will try and have a search for the thread later once tea is cooked and small person put to bed

The number 2 is engraved underneath the bottom plate….watch out for the mag spring when you take it off! The Gen2 mags seem to give better gas efficiency with out the need to trim the fill tube. Nothing to do with gas retention.

Best bet is to load the Python module on the Arduino as it is much easier to learn than C. Then get yourself the “Automate the boring stuff with Python” book and online course. I have developed a basic airsoft target game with a mini Arduino runninf C (with help from a friend who is a software dev) - those are two weeks of my life I am never getting back!

I have the Olight Valkyrie as a main weapons light (and the smaller 1 CR123 for the pistol) and while it is a great bit of kit and very bright it can be too bright and the reflected light from use in small, painted rooms dazzle the user! I have a scope flip-up cap (with the cap and spring / hinge wings cut off) holding a 2mm thick red tinted lexan over the lens - this moderates the output and preserves *some* of my vision! Easy to pull the cover off and dazzle the opposition if needed (say, outside or in larger spaces)

G&P reborn....again! Carry handle and classic fore end with BHD-type camp paint done in a hurry. Will be my go-to for woodland games (GBBR is NOT ideal when you need to put down lots of covering fire!) Now I need to find some metal STANAG mags in stock somewhere so I can paint to match!

As someone who tried to get them to come and certify a world record I can confirm this is not the case, they generally tell you that yours is too silly (really?! Have you seen some of the stuff they certify?) and then threaten legal action if you call it a "world record" with out them verifying it (even if you never mention the G word) Last email to them was pretty much summed up as "Go away in small, jerky movements'

Maybe use some PTFE spray (GT85 or similar) to make sure the weighted head and striker pin are moving freely as any friction will reduce the impact on the primer. I have an old AlphaTec and it just keeps running with zero maintenance...not even sure what you can do to them?!

I am using Magpulls on my M4 mags but also plan to try stuffing a chunk of pipe lagging in the bottom to raise them up a bit (also allows me to place empty mags “feed lips up” so I don’t grab them by mistake!)

If the mag corner is bent FFS don’t try and bend it back! I guarantee it will fracture 😢 Use a small file and file it flat a little at a time.

This thread gave me the kick I needed to get an SADF M83 chest rig. Probably one of the best purchases I have made! Can take M4 or AK74 mags easily, side pockets fit my timed and impact BFGs and the skinny pen pocket takes the reloading tool. Throw a tin of primers in the tiny pocket and I am set! Even with 6 (!) TM M4 gas mags and 2 BFGs it is comfortable with no hot-spots on the straps. My Viper Spiritus clone is ok with 3 mags in but add any more and after a while it starts to kill my shoulders. I will be keeping that for CQB and short games; for woodland / OPFOR / and long games the M83 will be the go-to 👍 I will be adding some Velcro OneWrap to the strap ends to tidy them up and might add an elastic section to the waist strap (along with cordura “concertina” cover) to allow for pie intake 😂🍔

Check the little catch on the mag is moving smoothly. Press down the bb follower then check that the little catch at the back of the mag moves up and down smoothly. It is easy for dirt to get in there and make it sticky. I have had some that were sluggish due to dirt and another where the corner of the mag was bent inwards half a mm and stopping it moving at all!

For that sort of money just buy a regular MWS, change the stock / rails / grip and get any bits you fancy Cerakoted in a suitable pimpy colour

I have found that the MP5 doesn't need a high mount sight due to the drop on the stock (even with face-pro) unlike the in-line M4 style. Can't imagine using a red dot on a high mount even with my giraffe neck! Also....lovely collection there! GBBs?

I tried one but due to latching and the issues of having controls inside the trigger guard (not a great idea!) I sold mine 😀

So what was it? Just in case someone else runs into the same issue!

I would start with selecting a hand guard and measuring the internal diameter and then working from there as that will dictate the suppressor diameter. You will also need to check the length of the hand guard vs barrel and see what overlap you need.

Baby blue paintpen on mags and rifle, BFGs are engraved. Plus I have enough pics and details of internal upgrades to back it up 😁

Stirling Airsoft Op ACRE at Gloucester prison. Being part of 3A and getting to clear C-wing at 2am then keep harassing the guards in the med block to disturb their sleep 😴

I am sure I have seen a cut away diagram somewhere. TBH it isn’t that complex and should be easy enough to reverse engineer from the principle. EDIT Found one, not the best but gives you an idea!

As Asomodai says, the FPS drop is a by product of the hopup giving more backspin to the BB (by pressing on it more) I chronoed my Cyma AKS-74U once with the hop in full and wondered why it was only 150fps! Then I remembered I had stripped it down and the hop always gets pushed on max when reassembling! Turned it off and back to 330fps 😂

The three prongs and 3 different screw holes (can see 2 in pic, at different levels) are a dead give away. https://www.fire-support.co.uk/product/gp-marui-mws-gbb-adjustable-piston-valve

The G&P adjustable stop has 3 different holes for the thin cross screw so it adjusts how far forward the valve sits and thus the power. I was getting 180fps / 260fps / 290fps on green gas and 0.30g BBs at 18degC on the low/mid/high settings IIRC. Stock TM bolt/nozzle/etc

Others have found that it gives higher power. I have used a RA Tech NPAS in a TM nozzle / bolt and found it pretty good at dropping the FPS. You need the black one, as the silver (WE) one is too fat to fit. I would check what is in the G&P nozzle to start with as they might have used the 3 position valve stopper (or get one for £9 from Firesupport) as this can be used to alter the FPS too. A spare nozzle and nozzle spring would be the minimum, I usually take a spare complete nozzle (easier to swap out) or complete bolt (even faster to change) Other than that taking the AEG as insurance might be a good move. I have found the MWS to be very reliable but if you have travelled to the other end of the country and still have 23hrs of game play left if would suck to not have a rifle!
