I already got the screw for the TDC mod and will do it in the next few days.

My new problem is the following: I just got my new hopup chamber and hopup rubber from ratech, adjusted everything properly, set the hupup rubber perfect in place and reassembled everything, but now the bullets just keep rolling out of the barrel, not every shot, but every second shot, disassembled the whole gun again, checked the hopup unit and every freaking thing, messed around with the hopup rubber a bit and reassembled everything, went fine for 3 mags then bullets started to roll out again.

Any ideas WHAT THE HELL the problem could be? Bullets come out of the mag properly, hopup rubber sits perfectly, and is not too thin so bullets get through rather easy and the hopup isn't working anywas so that can't be a problem.

Kinda desperate atm as a game is comming up and I want to go there with my main again.

I have a question about inner barrel. What type (and what length) of tight bore 6.03mm inner barrel can be fitted with this gun? Any recommendation would be helpful.

EDIT: And some information about R.I.S. fitting would be helpful too. Thanks.

Correct, you either have to file the teeth on the delta ring, or file a groove into the rail. If you stare at the pieces long enough, you'll know what I mean.

Thanks radge and beanie. I managed to fix everything by simply shimming the upper receiver and dust cover with electrical tape and heavily oiling everything. The bolt carrier is now well centered without too much friction, the dust cover opens during charging and the bolt catch works properly. I also ground the bolt catch 'tab' on the carrier down a bit because it was smashed and worn down inward to like a 45° angle. Hopefully the electrical tape holds up - I don't want it to be any more permanent than tape, since I'm hoping t_hum's bolt carrier will work without needing shims.

It's just too bad only you two responded to my question. I mean come on, no one else took the 30 seconds to check? Sigh...

Been discussed in earlier posts, the V2 bolts requires a smaller O-Ring to work properly. You have to use the stock V2 valve's O-Ring on the CVR to have it working properly.
