I did some testing today with propane and it emptied 2 mags on a single fill no problems. Try guarder powerup gas if you’re really struggling. On a side note, TNT buckings are very good.

@Shizbazki having owned 3 GHK m4’s, the mws’s outshoot them all day long, especially out of the box specs. If the hop rubber is black, there’s a good chance it’s a standard bucking. @camden I use propane, but power should be similar. I’ve ran guarder power up gas in mine in this colder weather and it brings the crispness back that it starts to loose. Black gas should be fine now. Wouldn’t be using it in the summer though as it’s super snappy on green/propane anyway. Ive never used one in an mws personally, but people swear by them. https://www.skirmshop.co.uk/250mm-604-crazy-jet-gbb-inner-barrel.html i have used them in my WE scar H and mk23 and had great success though. There’s a few good barrels out there, just remember if you’re keeping the same length, you need a tighter than standard bore to increase the power. I’d avoid the PDI raven though. 6.01 made it over 350 for me and the hop window is tiny

@camden My casv with a standard barrel is getting about 310 I think. Putting a 260mm crazy jet in it should boost you up if you’re trying to squeeze everything out of it. What gas are you using?

Very interested in that. I was holding out for a GBBR Famas, but I feel like I’d be waiting for eternity

You buy from the U.K. site?

Isn’t a real steel suppressor for an AK a controlled item?

You can get used 416’s and scar H packages for sub £500 used and they start off at £500-600 new, not sub £400 for me, that AK is £375 max

Don’t solid stocks need longer buffers? If so, G&P make one. I’ve got it on my mk12

Never owned one, but the general consensus is they work, but not as well as the standard TM ones

That’s the best way of doing it. You won’t see a great deal of improvement with the same BB’s though. The performance gain comes from being able to use heavy BB’s. That being said, in standard form with .28’s it will run rings around a TM recoil. Mk12 just got a service and a new bucking to try.

@Immortal .30 was about as heavy as I could hop on a stock nub. The bucking is good, just there’s only so much hop you can apply with a hollow nub. @xB0SHx I actually prefer that I key design. I modified an mws chamber to take one once with good results. That long contact patch will work great with maple leaf and TNT buckings

I’ve never heard of a place banning propane.. all green gas is propane and silicone oil. I’m not entirely sure what ‘blend’ power up gas is. It functions and smells just like green gas. I imagine it’s like Nuprol black, but I’ve never tried it. Gives about a 15fps boost and a much crisper cycle in this lousy weather. Even makes my Gas SR-25 run like a champ in the cold. A WE mp5k? I’ve got the pdw and love it. Heavy little thing though. That nub should be fine. Just make sure if it’s smaller than the window to center it well.

Excellent! What gas are you running? I’ve just been testing some guarder power up gas and it’s even better than propane in this freezing weather.

I’d fill it with gas before you put the spring and plate back on so you know there’s no leaks. That feed spring was a right fiddly bastard for me ?

I’ve done it with a 2mm Allen key before. You can put it in one of the two groves and twist.

2 reasons.. it helps with FPS consistency to leave some of the tube. But most importantly... they’ve glued them in that badly, you’ll never get it out anyway ? trim it to 5-10mm above the brass valve inside Just put a screwdriver in one side. I found they weren’t particularly tight.

@rocketdogbert extreme airsoft. I’m enquiring with a friend about getting one at cost price. @Immortal you don’t need a valve key to do the green gas mod, just an Allen key. I’d advice cutting the tubes and not removing them all together.

Found an all black one for £129

Me ? where’s the best place to get an AW drum?

If you’re keeping it standard then the mws. If you’re gonna change the rails anyway may as well go for the cheaper option

If you aren’t arsed about the quad rail, fire-support has an mws m4a1 for £459

They aren’t cheap, are they ? I’m thinking of trying a new hop combination with a custom nub very soon. Will report back how I get on.

2 threads gap on the buffer tube is right. Regards to the bad lever... I don’t like the idea of them at all. In terms of the MWS, you’re adding weight to the bolt stop assembly. The ZET plate will have to lift that extra weight, which will effect bolt lock performance. Having bled profusely for hours after a Scar H bolt bit me, I don’t want any extra ‘help’ releasing the bolt when I don’t want it to.

That looks great. I had the same issue with a z parts suppressor on my VFC mk12 flash hider. I bought the VFC suppressor instead

What can’t you get tight?
