Thread adapter
Good
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.

Worked as intended, excellent machining and quality.
Excellently machined and fit perfectly. One from another vendor failed to thread on. Thanks for a quality product!
Worked perfectly, threaded easily onto the pre-existing 24x1.5 threads. 5/8x24 muzzle device then mounted easily onto the adapter. Easy to install, accurate, and well made.
This is perfect for my AK-102. The mount fits snugly with no wiggle so I can safely mount my suppressor.
Very quick shipping and fits as described. Perfect
This adapter blows those loosey goose detent adapters out of the water. No timing need, great snug fit, and is concentric with my Arsenal SLR-106F.
I use all of griffin armaments products & this is no exception
Bought this for mounting my Sandman-S on my PSA AK104 GF4. Had no issue with concentricity and everything worked flawlessly. The only issue I had was the AK heating up to the point where the muzzle device loosened and could be threaded off. If there was a way to cut a small detent on this converter it would be more perfect than it already is. Otherwise it is a great product, paired well with the KNS adjustable gas piston for suppressed fire. I would suggest this to everyone looking to suppress an AK and not wanting to buy a dedicated AK suppressor
It was awesome. Worked perfectly
