SRS Piston Cup with air brake

SKU: SBA-BPS-15 Categories: ,


An airbrake is cutting the air flow before the piston hits the bottom of the cylinder, creating an air damper that will reduce the impact noise, possibly at the cost of muzzle energy reduction.


This product is coming 3 brakes of different length, the longer the brake, the higher the noise reduction.
