The ATA Venza incorporates a newly designed Gas Pressure Control System (known as GPCS) as well as reciprocating barrel technology to provide the perfect combination of performance and dynamic appearance. This new system uses larger gas release valves that allow gas to escape faster when firing heavy shot loads. When fired with a heavy load cartridge the barrel moves backward and at the same time gives the first movement to the breech bolt.

This movement also opens the gas valves to exhaust extra gas pressure from the forend side vents and forend cap holes. In this way the recoil is reduced, and the stability of the gun is controlled by effectively minimizing muzzle jump. This feature also increases the accuracy in serial shots to one or more targets.
