i think this was just made to be a mag, not a real gun.

Bartboy (author)The Jamalam2008-09-11

no, it has a fireing pin and a barrel

Fatty1616 (author)Bartboy2008-09-11

it is do be used in your own design because it is fairly powerful and it doesn't jam so just build the gun around it if you want me to post a picture of a gun using it I can
