The AP51 PDW is based on iconic HK51 PDW developed by Heckler & Koch for Germany and its allies during the Cold War. The AP51 is chambered in 7.62x51mm and utilizes a roller-lock delayed blowback action once renowned for its light weight and simplicity. The AP51 PDW is equipped with a Navy style assembly consisting of an ambidextrous safety selector, MP5-compatible wide handguard, standard G3 trigger set-up and bird cage style flash hider to give it a classic Cold War look. This model features an all black finish and includes one 20-round G3-style magazine. This firearm is compatible with both 7.62x51mm NATO and .308 Winchester ammunition.
