Griffin Armament Fixed Barrel Mount - 1/2x28

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.
