Made from the un-serialized halves of two guns, and using a .22 barrel from ebay, this single shot break action assault pistol is sure to please (and disgust). Make sure to leave it in the full-auto position so you can shoot those single shots faster.

Originally made Oct 9, 2020, in my dorm room.

This has undergone several iterations and now uses a pure-3d printed barrel, meaning one less part to buy. The G3’s hammer is cocked manually after opening the gun, and the flat-topped upper’s gas tube hole makes for excellent backup sights (a corresponding cutout is made in the rear cap).

A self contained striker module holds an M3 bolt captive and under spring pressure, acting as a firing pin, all nestled in the front section of the upper. This threads into the barrel collar, which threads onto the upper’s barrel nut threads.
