KF-5 Goes Super Safe
This video details the KF-5, a 3D-printed MP5 variant, and its 'Super Safety' modification. The custom clip enables the safety to work with the MP5 bolt geometry, though it causes short-stroking. This limits the iconic MP5 slap and slightly increases the rate of fire. The build features a KAK muzzle device for recoil control and has undergone extensive testing.
