Internals are more or less unmodded. Once I took the original barrel off the restrictor came with it.

Here's the three sizes of brass and the pvc in order of smallest to largest. I had to cut the middle of the biggest brass because I didn't have enough (or $2.50 to go get more. Welcome to college.).

Here's the brass all together... I guess for those of you who didn't understand what I had to do to the biggest brass to get it to cover the front and back.

Completed gun, breech off.

Breech on, cocked. Ain't she a beaute? I'll have ranges actual ranges soon, but right now looks like 75 ft accurate range, and I might be able to hit 100 at an angle with no accuracy at all.
