your diagram in the initial post... is essentially a Crossman C11 and it's airsoft variants. check out the parts diagram. great design- cheap, high velocities.

and this would be different for an CO2-powered automatic sub-machinegun ..how?

i didn't say it was different- i said that's the reason

:) i'm loving this... you guys are a crack up. nothing wrong with shooting game with something like the GSMG- any and all activities should be in the pursuit of happiness... so it you want to hunt thumper with a GSMG- feel free. it will no doubt 'do the trick' and put a smile on your face in the pro...

I've been a long time lurker, and your archives always answer the questions I come here for, so there has never been a reason to post.
