Although the KOR heavy machine gun is similar in performance, construction and appearance to the NSV heavy machine gun of the former Soviet army, the internal mechanism has been extensively redesigned. The locking mechanism was changed from the original horizontal rotating breech locking to the Kalashnikov style rolling bolt locking mechanism design. In addition, the pneumatic actuation system has been revised, and the baffle in the muzzle brake has been redesigned. These improvements have resulted in a much lower recoil than the NSV, allowing it to be more accurate when firing sustainedly. The feed direction can be easily changed from a right feed to a left feed.
