Fixed mounts threads directly into your booster housing and allows you to remove the booster piston, spring, and piston retainer and use this single component on your fixed barrel firearms. Sprung pistons should not be used on a fixed barrel firearm as this will cause the booster assembly to batter itself to destruction. This part saves about an ounce of weight versus running a booster piston and fixed barrel spacer.

5/8x24 is a good fit to direct thread to 300BLK subsonic and .357 guns. 1/2x28 would work for 1/2x28 threaded 9mm carbines.

This mount is not intended for use on any higher pressure cartridges like 300BLK supersonic or 5.56/.223. 

If a fixed mount isn't your style you can spend a little more and option for a 3 Lug QD system

Made from 7075 T6 aluminium.

Available in 5/8x24 and 1/2x28

Compatible with the Optimus, Resistance, and Revolution series of suppressors.

  • 7075T6 Aluminium

    Perfect for my Revolution on my 300 BLK.

    Published by Greg Norman on 26th Jun 2023

    I bought this so that I could use it on my Ruger American Ranch 300 BLK. It works perfectly with Sig Sauer 200 gr subsonic. Everyone needs to remember if you are using your Revolution with 300 BLK use [ONLY] subsonic ammo.

    Revolution Fixed Mount

    Published by Robin Bagesse on 15th Apr 2023

    Shipping was really fast. Fit and finish is Griffin standard excellence. The mount is used to attach my Optimus to a Bergara BMR 22 Mag Rifle. Installation is as easy as removing the spring and piston from the booster assembly, screw the unit into the suppressor, install the 22 end cap and enjoy.

    These well machined and finished components greatly expand the capabilities of the Revolution suppressor. A must have for anyone who desires to mount this can on approved rifles.

    Fit and finish are excellent

    I purchased this mount so that I could direct thread a .45 Revolution suppressor onto a .45 SBR. It replaces the mount that came with the suppressor perfectly.
