thats so cool nice job man
i'm going to start building a paintball sniper in a few days and i saw the trigger system u used on your gun. i was also searching through some other posts and saw some other guys used it as well
Whats it called?

yer i got a bike valve (from the nearest sisters bike hehe), putting it into pvc, like 100-150 psi of pressure.

my gun looks like ur gun but im still learning on how to make air guns and im not confident about the bike valve i think its going to shoot out when i start to put air into it so wat did u do Joe??

very very nice gun good job

r u sure that'll hold it tho?

hey guys in new here and i'm making a marble shooting air gun and i need 2 pump the air chamber up to 140 psi or at least 100. and i don't know how to put the valve on the end of a PVC lid without is blowing my face off any suggestions???
