Plans for new rifle - NEW QUESTION

[Thursto]

oh alright.

Do they need to have o-rings?

and ill probs cast one out of epoxy, but it will still be heavy.
Is it possible for it to crack? and whats the best way to attach the sealing face?

I'd stick away from the rubber corks mate. I got right into em' for a while but realised they aren't at all practical. They need constant lubing otherwise they stick like a [female doggy], plus they're heavy, and hard to get perfect fitting in your pistin housing.

I've really have had no problem with them, the lube does dissipate after a few shots but i haven't noticed any performance loss, they do get stuck but as you pressurize the gun the piston will seat correctly. (pressurized behind piston) Id advise that you pressurize from behind so that you don't have to worry about springs and what not. This is more practical for higher pressure launchers and with a rubber piston, there is no need for a spring and or bumper nor do you need to worry about arsehole sealing faces poping off.

Take your time in making your piston and it will last you countless shots
