When paintball enthusiast Mad Matt gets bored, he looks at his collection of replica guns. And when he looks at those? He figures out new ways to shoot people with them.
Mad Matt had a Stargate SG-1 version of a P90 submachine gun sitting around, and toyed around with the idea of making it a paintball gun. He first created a 3D model of it in 3ds Max and then planned out what the innards would look like to turn it into a working paintball gun. Once his plans were in place, he easily slapped together the real thing, taking the snaps you see above.
Living up to his apocalyptic pedigree, Mad Matt has proven to be quite crafty indeed.
