my pvc shoot gun

Unread postAuthor: oneocim » Sun Nov 17, 2013 11:03 am

Hi guys, this is my new gun, scaling up from my previous gun. It is 3/4 inch piston inside 1 inch brass T with 1/2 inch seat. The barrel is 1 inch, used max with 80 psi :( . Multi shoot (attached to commercial air compressor), chamber filling, hammer valve for piloting, breech loading.

A little ghetto, but it clearly works and I like it :)

Thank you jack. Yes, it is ghetto, i should practicing more on painting and stock making. I know I have seen that kind of post here but can't find it anymore.
And bravootome, free ammo, nothing better, also helping the environment for planting more trees ha ha. My gun is not so powerfull so most seeds are intake. According to GGDT I should be able to plant tree 185 m away.
