1 barrel, 2 guns

Unread postAuthor: Ranger » Wed Jun 16, 2010 6:21 pm

After looking around on the fourm I stumbled upon http://www.spudfiles.com/forums/preload ... 14802.html

I figured that I could make something similar to his design, so I came up with a burst disc gun that uses heavy duty duct tape for the disc. The barrel is 3/4" PVC with a Tee at the breech to act as a coupler for to chamber and a handle, the tee also has a nail to stop the projectile from going all the way down and going into the tee. At the front of the barrel I heated it up over a fire until it became soft and then shoved it onto another piece of 3/4" pipe to make a "muzzle break" of sorts. The Tee and the chamber have been sanded down so that they can fit together when the tape is between them. It uses a modified blowgun for the trigger that I can connect to my compressor or a modified air bottle. The gun works by squeezing the trigger, then air fills up the chamber until the disc pops launching out the projectile. It makes a really loud bang because the disc doesnt pop until about 80 psi.

BD1 (Burst Disc Mk 1)




After building this gun it became my favorite, I could carry around the air bottle and get 10 shots out of it before I had to refill. I liked the gun but I didnt like having to lug around the air bottle or having to connect to my compressor.

One day, I had my air pistol and my burst disc out. I started looking at them, I put the barrel of BD1 on my air pistol and viola. A new gun was born 8) I sanded down the barrel on the pistol to make it a loose fit in the tee like I did on BD1 so the tape would fit inbetween them.

This new gun got a new designiation BD2 (Burst disc Mk 2) so now it can either be called PP2 Or BD2 :? .It may not have the range of AR1 or BD1, but the range is about 3 times that of the pistol.

This is now my favorite gun, its light, easy to carry, and easy to use


2 guns, 1 barrel :D

AR1 And PP2
