SRS / TAC-41 Piston Cup with air brake

Improved piston cup for Silverback SRS / TAC-41 sniper rifles. It serves as a seal and rubber pad at the same time. Made of NBR (70°).

The main advantage of this impact head is the air brake. It is used to silence the weapon. Just insert it into the piston head, there is no need to glue / screw anything. When fired, this brake clogs the muzzle of the cylinder head, whereby the weapon is "choked" at the last moment before the impact of the piston and the piston almost stops on the air cushion due to the pressure and then, at a very low speed, hits the cylinder head. Although this solution cost a small loss of performance, but the results of silencing the shot is incredible.

The package includes air brakes in three sizes. The longer air brake, the greater the silence. So you can choose the ideal ratio between silencing the weapon and its performance.
