A home-made gun often made in a garage or a machine shop. While they are a fun project their actual use is to arm people in 3rd world countries who can't buy guns. Also in America they are completely legal and can be made out of anything that can contain a gunshot. Basically a fun home-made project for any gun nut.
Hey dude come over to my place I got stuff to make Garage guns and some targets to shoot.
I should probably also state that as their barrels arn't rifled Garage guns Aren't very accurtate
