A knex PM-63 based of black ops. This was a quick build and lacks accurate iron sights. Uses a "block behind handle" mech but the magazine is fake. Works well as a single shot though but i had to make the handle as real as possible. It features a folding grip (and stock but is not shown due to picture space. Can also be modified with my grenade launcher for those of you who like the tube.
I got lazy with my picture quality:)
