AK Thread Adapter AK47 AK-47
Thread Adapter OD 5/8x24 ID M14x1.0 LH Tools Required- 17mm Wrench Finish - Black Nitride This adapts your metric 7.62x39 AK barrel to the standard 7.62 thread pitch for muzzle devices and suppressors.
The latest version of the AK thread adapter has been designed to index on the muzzle of the barrel, rather than the rear sight base. This is to ensure best possible angular alignment of the muzzle device.
It is important to clean any buildup on the muzzle before installing thread adapter to ensure that clean, surface-to-surface contact is made between the adapter and muzzle.
