  • Design and operation concepts

The weapon incorporates a number of non-conventional design and functioning solutions involving low expenditure of materials, i.e.:

  • round being a part of the action;
  • shockless “flick” chambering;
  • gas powered extraction of fired casings;
  • partial time-matching of these operations.

The main feature of the cannon is an independent water-evaporating cooling system of the barrel.

  • Unique design

The unique short-recoil action minimized the weapon weight and allowed achieving the highest firing rate per barrel among 30mm cannons. The ring return spring and dual-action hydraulic brake efficiently dissipate the excessive energy of the mechanism parts stabilizing the action during burst discharge. Both right- and left-hand feeding, electro-pyrotechnical recharging and ammunition counter are available.
