General characteristics of the system

The purpose of the system is to serve as company level anti-tank armament. It uses a semiautomatic breech with forced opening. Insignificant amount of recoil is achieved using a roller principle, where the shot is fired while the barrel is moving forward, which is done with a special spring* and a muzzle brake.


The gun is equipped with wheels to move around the battlefield. For long marches, the system can be easily taken apart into 2 pieces or transported whole with the carriage in travel mode.

The gun can easily be converted to be carried by people or on a horse.
