- barrel sealing valve in a brass 1/2" T and nipple
- piston: marker butt with glued rubber sealing
- 7,2 x 420 mm barrel
- pilot: self made out of an old bronze valve
- fill valve - quick-connect and ball valve
- chamber - pipe from a bicycle seat welded to iron nipple
I am not sure what is the preassure, because i dont have manometer. The scope is attached just for the photos, but i'll fix it latter. The barrel is bronze pipe glued in wider aluminium pipe to protect it form bending. The connection between the barrel and the gun is from the same type of valve that i used for the pilot soldiered on the bronze pipe. For ammo I use short pieces of 7mm nails, because i can't find proper size lead shots. At the moment, the gun is not very accurate because I don't have working sights, so I hardly hit bottle size targets 20 meters away.
The main disadvantage of the gun is that I must pump it for every shot and it is muzzle loaded. Also the trigger is very hard to pull. Also the pictures order is backwards but i dont know how to fix it
Sorry for my broken english.
