npas for ghk aeg to gbb conversion kit

[menissan86]

Is it possible to fit an npas to the ghk aeg to gbb m4 conversion kit (if so can you recommend one) as the site I use won't let use the gearbox because it's shooting at 350fps.

Thanks Adam

I don't think there is a NPAS that would fit this, I might be wrong (hope I am, that would be amusing). The floating valve looks like this:



What gas are you using?

I've been useing green gas which is firing too high that said 144a gas dropped the fps down to 310ish, think I'll have to stick with the 144a and maybe get a barrel extention that hopefully will push the fps up to 320-330. I didn't realise how strict sites are on gbb rifles.

I wonder if FG airsoft LFS disks might fit and help restrict gas flow?

Did you have any running problems using the 144a gas at a game?

Just to confirm I have now operated my ghk conversion on 144a and it runs fine. If anybody needs to lower their FPS that is the easiest way I can see. With abbey ultra at around 18c it clocked 340 with a Madbull tightbore 363mm barrel.
