Griffin Armament Pistons + Spacers


SKU: GriffinPistons Category:


These pistons are heat-treated with a rust inhibitor and constructed of 17-4 steel for ultra-long life and reliability. For use in the Griffin Armament Revolution and Resistance silencers.
The Fixed Barrel Spacer replaces the spring on Revolution and Resistance silencers to lock the piston from traveling when the suppressor is used on a fixed barrel firearm. The spacer should only be used on a fixed barrel firearm.


It is important to intermittently clean and lubricate the exterior of the piston to ensure smooth reciprocation with the O ring in the piston retainer.
O-Rings should be replaced intermittently when worn to ensure alignment of the silencer with the booster assembly. Failure to replace damaged or worn O-rings could result in a baffle strike or damage to the piston components.
