No problems with the M4 (currently stripping and polishing ) however I remember that each shot slowly loosened the stock tube. Anybody else been having this problem? Any remedys?

Does anybody know how the RA TECH NPAS BCG copes on 134a gas and what fps can be achieved using 134a and an NPAS BCG? I ask since 134a is readily available to me...

Right so all the above plus 7 GHK mags (or similar) I have to say this is quite possibly my favorite thread on the whole forum, full of nice people, no spam, decent reviews and tips, and above all a perfect example of how a forum should work... if only the whole forum was like this

So if I have read all the posts correctly... A RA TECH complete NPAS BCG, Steel Bolt Stop and G&P Hop Unit and rubber should be all that NEEDS to be replaced to make this a realiable skirmishable piece of kit?

Anybody tested the Chinese made metal hop up chamber? If so, any issues? http://www.crw-airsoft.com/metal-hop-up-se...4gbb-1629-p.asp I'm thinking this may be a better purchase as if anything should break its cheap to replace...

Could I just buy this and fit it to the standard bolt & bolt carrier? Which metal hop up is the easiest to use?

Which would you reccommend? NPAS kit with Alluminium Nozzle w/simple adjust valve NPAS kit with Plastic Nozzle w/simple adjust valve RA TECH N.P.A.S with Simple Adjustment Valve Complete Bolt Set for WA M4 I'm guessing the complete bolt, but do these fit? Also, did we establish which is the best hop up set to use?

My not so little baby... Im ready for the inevitable jokes... P.S. Thats a silencer not the long barrel

Comments please guys.
