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

    Works Great

    Published by Alex on 27th Jul 2020

    Purchased this so I could use my Rev45 suppressor on my Sig MCX Rattler Canebrake. Worked perfectly. Just unscrewed the piston that was used for a pistol, this screwed on and onto my barrel.

    Looks like it’ll do the job

    Published by Colbe on 13th Jul 2020

    I haven’t used it yet but it seems to be produced very well along with the rest of my rev 9.
    This accessory allows me to mount my suppressor my scorpion. I’d like to say permanently but who knows if it’ll be forever?

    Fixed mount

    Published by Rob on 20th Jun 2020

    I found out the hard way do not use an ultrasonic cleaner with purple power to clean the mount or the suppressor. I did and it took the finish off.

    Does its job

    Published by Ted on 5th Feb 2019

    Everything you buy from Griffin is top-notch quality and these fixed mounts are no exception. My advice: get some Horse Jipe (best product name ever) and put a little on the threads. It will help you remove the mount when the time me, I found out the hard way!
