Silenced Piston head made with CNC machining. Thanks to the implementation of the abutment o-ring, the sound will be lowered by making the ASG very silent, while the innovative conical shape without the presents of the anti-vacuum holes on the front minimizes the air-consuming in compression phase, while the central body made to obtain a 60° cone in a way that all the air in the compression phase is concentrated at the base of the cone, pushing it and sending it directly inside the the cylinder head’s nozzle, avoiding the formation of air vortices. Ideal for low fire accruals or Sniper configurations.
