  • Accuracy and consistency

The accuracy and consistency of firing are significantly enhanced due to employment of effective muzzle break and shock absorbing of the recoiling barrel, reducing oscillation of the gun mount at the moment of round discharge, along with moderate rate of fire.

  • Design and operation concepts

The weapon is highly reliable due to single-barrel gas-operated action. The fixed receiver facilitates the ammunition belts feeding into the gun. The ammunition load is consumed efficiently due to selective feeding and firing rate alteration capabilities implemented in the gun. The long barrel contributes to extended point-blank firing range.
