Griffin Armament 24mm x 1.5mm thread adapters give your compatible AK platforms 1/2x28 or 5/8x24 threads. These aren't hardware store grade adapters. We analyzed dimensions from several eastern European countries to design 17-4 billet machined adapters capable of rendering AK's suppressor and mount compatible with devices requiring alignment and timing like brakes and compensators. These adapters feature a raised surface that interacts with the muzzle face of the barrel rather than the front sight base, permitting vastly superior theoretical alignment accuracy than the detented and loose, rattle-trap devices common to these systems. For rifles that have clean muzzle faces that are perpendicular to the bore, this will permit excellent alignment to occur. We recommend 50ft lbs of torque for installation, and qualified gunsmith installation and alignment checks prior to suppressor use. 27mm wrench flats are provided for ease of installation.

1/2x28 units are compatible with 5.45 and 5.56mm 24mm AK's, while 5/8x24 units are 7.62x39 and lesser caliber compatible. It is the buyers responsibility to know the thread pitch of their AK type rifle/pistol.
