Grozny Arms Corp. Berkrut AS-20 20mm Anti-Armor Rifle. Built for taking down heavily armored vehicles, the Berkrut AS-20 fires the 20mm Hispano round. The round is so powerful, that it requires the rifle to incorporate a backblast tube to reduce the recoil in addition to a large barrel compensator. The rifle is fired from an over the shoulder position and as such the scope is offset to the side.
