my all metal sniper rifle

Unread postAuthor: roughboy » Wed Jun 13, 2007 9:48 pm

This is my all metal rifle.it's a piston barrel sealer,the plastic ball valve on the barrel is the ammo loader it is not my idea i took the idea from someones cannon on this froum (can't remember the name) i can take it to 160psi coz thats the max psi on the sprinkler valve and the sprinkler valve is the weakest point on the rifle.but for now i only take it to 100psi. at 100 psi this rifle can shoot heavy round lead balls without even see the ammo

that looks really heavy. its gotta weigh at least 15 pounds. its a very nice gun, but heavy.

you have any idea how fast it shoots? it looks deadly. :twisted:


can we please see the piston, thats the best part in my opinion.

I don't know how fast it shoots don't have a chrono.
The piston is a piece of pipe that fits the T perfectly, the sealer is a rubber washer and a piece of tire rubber hooked up with bolt, nut. it seals great theres no leak and yes the gun is heavy but very very powerful.

Damn man its nice to see a person on here with an interest in building snipers :P Its nice and I reckon a proper piston valve would be suiting of it so you can crank up the power on the beast :twisted:

P.S. I gotz a new computer ^-^

i think the sprinkler is a bit over kill and a high pressure ball valve would work just fine other than that it looks nice
