The Griffin Armament 5/8×24 Suppressor Thread Adapter (brand part no. TA1515824 5/8X24) converts AK-47-style 14x1mm left-hand and HK-style 15x1mm right-hand threaded muzzles to the far more common 5/8×24 thread pattern, opening up your accessory options to the broader U.S. aftermarket. Finished in black, it’s a straightforward way to run a standard 5/8×24 muzzle device or suppressor mount on a surplus-pattern rifle without a gunsmith re-threading the barrel. Because these surplus threads require a muzzle face index for perpendicularity, this adapter is not compatible with muzzle devices that require timing.
