a pneumatic sniper rifle.
Step 1: Materials
in this project i used;
1 coke bottle
2 valve from nerf gun
3 bike tire valve
4 curtain rod
6 spray paint (optional)
Step 2: Chamber and Cap
drill a hole in the cap just big enough for a snug fit for the bike valve.
drill a hole in the back of the bottle and fit the tube from the valve to the hole
Step 3: Barrel Ammo
i used a peice of curtain rod with duct tape for a barrel.
but u can use anything that will fit
put the other end of the valve into the barrel and snap it in place
try and make some darts that fit. i make some out of peices of entenne and sock
Step 4: Loa and Fire
load your dart through the back and pump it up and fire.
dont shoot people, this could realy hurt someone
Step 5: Paint (optional)
you can spray paint it if you want.
i did and it seemed to reduce leekage somehow
