Fixed mounts allow you to remove the booster piston, spring, and piston retainer and replace with this single component to use 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 guns. 1/2x28 would work for 1/2x28 threaded 9mm carbines.

If a fixed mount isnt 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
  • For use on Fixed Barrel firearms

    Does its job

    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!

    mounted and works great.

    Published by dwb on 10th Sep 2018

    Bought extra direct mounts for my Rev 9, to mount on a rifle and MP5 clone. 3- lug wont work on POF MP5, too much paint. However the direct thread mount worked well.
