Instructables
This Sniper Rifle reassembles the 25 mm Sniper Rifle by irWinner, which i give all the credit in the world to, except the barrel size and a few corners i cut =]

Major credit to everyone at spudfiles.com who helped me fix my sprinkler valve problem.

Modded Sprinkler Valve trigger

Step 1: Materials:

I can't stress this enough

a rainbird or watermaster sprinkler valve.
apparently any other kind won't work because of a guide rod inside the others.

1in. piping
a 1ft. piece of 2in. piping
