The Heckler & Koch HK94 is the highly collectible semi-automatic civilian version of the legendary MP5, manufactured in West Germany and imported into the U.S. primarily during the 1980s. It uses HK's renowned roller-delayed blowback system and retains the classic MP5-style receiver, rotary diopter sights, cocking system, and iconic profile, paired with a 16.54" barrel for the U.S. commercial market.
