Keeping Traditions Alive Since 1953

The 14×1 LH thread pattern on AK style rifles made sense back in the day, but it locks you out of nearly every modern suppressor and muzzle device on the market. Griffin Armament's TA1415824 thread adapter fixes that by converting surplus 14x1mm left hand muzzle threads to the 5/8×24 right hand standard, the same pitch used on most .30 caliber cans, brakes, and flash hiders. Thread it on, torque it down, and your old warhorse is suddenly speaking the same language as everything else in your safe.
Here's the thing about surplus rifle threads: they index off the muzzle face rather than a shoulder, which is why cheap adapters tend to sit crooked and cause headaches with alignment. Griffin builds this adapter with a proper thread shoulder on the 5/8×24 end, so muzzle devices that need timing can be set up correctly with shims. The 3/4 inch wrench flats let you get real installation torque on it with a standard wrench instead of fighting it with pliers and hope. That attention to detail matters a lot more when there's a suppressor hanging off the end of your barrel.
Because the adapter squares up against the muzzle face, that face needs to be clean and perpendicular to the bore for everything downstream to align properly. Most AK muzzles are fine, but it's smart to check bore alignment with a rod before sending rounds through a suppressor, especially on rifles with mixed-parts histories. Once it's installed and verified, a lot of folks just leave the adapter in place permanently and swap 5/8×24 devices on and off as needed.
Griffin has been machining suppressors and mounting hardware since 2005, and this adapter is made in house at their Watertown, Wisconsin facility. It wears a black finish that blends right in on an AK, and it's covered by Griffin's lifetime warranty. For the money, it's one of the simplest upgrades you can make to bring a com bloc rifle into the modern muzzle device world.
If your rifle has standard AK pattern 14x1mm left hand muzzle threads, yes, this adapter threads right on. It converts those threads to a 5/8×24 right hand interface for common muzzle devices and suppressors. Just make sure your muzzle face is clean and square to the bore, since the adapter indexes off that surface.
That's exactly what it's designed for. Once installed, any 5/8×24 direct thread suppressor or mount can attach to the adapter. Before firing suppressed, check bore alignment with an alignment rod, since AK muzzle faces can vary from rifle to rifle and alignment is on you to verify.
Yes. Unlike the bare surplus threads on the rifle, this adapter provides a proper thread shoulder on the 5/8×24 end, so devices that require timing can be indexed correctly using standard shim kits. The 3/4 inch wrench flats make it easy to torque the adapter down properly during install.
Most people install it once, torque it down against the muzzle face, and leave it in place permanently. From there you can swap 5/8×24 brakes, flash hiders, or suppressors on and off without disturbing the adapter. A drop of thread locker on the 14×1 side helps keep it put if you plan to remove devices frequently.
