Well since I left the car audio industry I have had a full time job being a robotic welder programmer (boring). but I also opened a new business as of last year. It has been pretty slow up until about 6 months ago. My business is Sin Arms and I sell reloading accessories but more importantly I make and sell custom barrels for Savage rifles and I am now getting into AR15 barrels. Its a lot of fun and I get to play with guns all the time. I am still working as a programmer but I would like to do this full time eventually. here are some pics of what I have done.
We took a 2 liter soda bottle and taped a paint ball barrel to the end. Between the soda bottle and the barrel we put a little stop. Drop the paint ball down the barrel, walk up to some unexpected person and put the soda bottle against your leg, smash the bottle with your other hand.... bam!
Doesnt shoot as hard as a gun, but it will break the paint balls!
