The Griffin Armament Revolution Fixed Mount in 5/8×24 (Griffin Armament part no. GAFM5824) is a direct thread mount that threads into the booster housing of a Griffin pistol silencer. It lets you remove the booster piston, spring and piston retainer and run this single component on a fixed barrel firearm. The mount is made from 7075-T6 aluminum, and Griffin says it saves about an ounce compared with a booster piston and fixed barrel spacer. It is compatible with the Optimus, Resistance and Revolution series of suppressors. This listing is the 5/8×24 thread.
