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 :
Was looking for a piston for my AK 9 mm and I needed something that will keep it concentric and this were great. KP-9 with Cash9k with fixed spacer. Was a tight fitting pistol in my suppressor but it worked flawlessly, very happy with this part.
Good price easy to install and works perfectly
Works great to attach my revolution 9 can to my 19x MOS and my 43x. Yeah direct thread takes a few seconds longer to attach, but I don’t need any adapters
Precision machined as you would expect from Griffin. Perfect fit and function.
Works as advertised! Direct fit on Fn45 Pistol. Works great and easy to install!
Super easy to install and works perfect on my FN 510 tactical. The piston was the only accessory I needed to adapt my bushwhacker. Awesome products!!
Very well machined and works well.
Had an anomaly with the piston and required a new one. It was replaced under warranty. Had it in 4 days. Super responsive. Thanks
Delivery was very fast
I have these installed in a CGS Mod 9SK and a Rugged Obsidian 9. Both suppressors function flawlessly with no baffle strikes or suppressor walk off. Makes securely swapping between weapon hosts quite easy.
