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 Kalashnikov suddenly plays nice with the same gear you run on everything else in the safe.
Here's the thing about original AK muzzle threads: they index off the muzzle face rather than a proper shoulder, which is why timed devices like brakes never sit right on them. Griffin designed this adapter with a real thread shoulder, so muzzle devices that need correct clocking can be timed the normal way with shims. That is a meaningful difference over the cheap adapters floating around, which tend to be loose, sloppy, and a genuine liability once you hang a suppressor off the end. Alignment matters when there is a baffle stack in front of your bore, and Griffin builds these to the kind of tolerances a suppressor manufacturer has to hold.
Installation is refreshingly simple. The adapter includes 3/4 inch wrench flats, so you can put proper torque on it with a standard wrench instead of fighting it with pliers and hope. Since AK muzzle threads from different countries and factories can vary a bit, it is smart to confirm alignment with your suppressor before sending rounds, standard practice for any AK muzzle setup.
Griffin Armament machines these in Watertown, Wisconsin, and backs them with their lifetime warranty. For the cost of a decent range lunch and change, it is the easiest way to bring a classic platform up to modern muzzle standards.
Yes, and that is one of its biggest advantages. Original AK threads index off the muzzle face and have no proper shoulder, so timed devices never clock correctly on them. This adapter provides a true thread shoulder, letting you time 5/8×24 brakes and flash hiders the conventional way using shims.
Yes, any direct thread 5/8×24 suppressor will spin right on, which covers most .30 caliber cans. Because AK muzzle threads vary between countries and factories, Griffin recommends checking bore alignment with your specific suppressor before firing. An alignment rod check takes a minute and is cheap insurance.
It threads onto your existing 14×1 LH muzzle threads just like the factory slant brake did. Built-in 3/4 inch wrench flats let you apply proper installation torque with a common wrench, no special tools needed. Remember the original threads are left hand, so the adapter tightens counterclockwise onto the barrel.
Yes on both counts. Griffin Armament machines these at their facility in Watertown, Wisconsin, the same shop that builds their suppressors. It is backed by Griffin's lifetime warranty, so they will repair or replace it if it ever becomes damaged or defective outside of misuse or normal wear.
