These custom thread adapters can be used to 1/2-28 rifles up to 5/8-24 thread pitch, so you may use 7.62mm suppressors in subcaliber role on AR15 and other 5.56mm rifles. Steel construction with sturdy wrench flats, in a dark gunblued finish.
These are ideal if you want to run your direct-thread 7.62mm suppressor on a 5.56mm rifle threaded in 1/2-28!
We recently contracted with CNC Warrior to make these for us - and the quality is excellent. The CNC Warrior adapters also have 13/16 wrench flats on the rear of the part, so it's easy to get them tightened down on your 1/2-28 barrel.
