These Pistons are considered legacy technology parts but are available for users who choose not to upgrade to either the CAM-LOK® (Covert Application Mount - Locking) Universal Piston System or the EZ-LOK™ Universal Rapid Index QD Piston Attachment System. These are available in popular but limited thread pitches. 

These Pistons are for use with the Revolution™,Resistance®, Optimus® 9mm, and Bushwhacker® 46 in their pistol configurations. 

It is important to intermittently clean and lubricate the exterior of the piston and interior of the booster housing 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.

Piston are H900 heat treated with a rust inhibitor. Please note, color and color pattern will vary due to the heat treatment.


Features :

  • H900 heat treated for improved durability and wear resistance 
  • 17-4 stainless steel material

    Like everything Griffin makes, this was high quality. Running it in a Rev 45 mounted to a Glock 22.
