Griffin Armament Revolution Pistons


These Pistons are required for use with the Revolution 9 and 45 silencers for pistol function.  The Revolution 9 ships with a 1/2×28 piston and the Revolution 45 ships with a .578×28 piston.


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.


Pistons available in the following thread patterns:

  • 1/2 x 28
  • 13.5 x 1mm LH
  • 9/16 x 24
  • .578 x 28
  • 16 x 1mm LH
