Now you can mount any 5/8″-24 end-of-barrel accessory on your rifle’s non-threaded barrel—including muzzle brakes, flash suppressors, compensators, sound suppressors, or fake flash hiders and suppressors—with this high-quality barrel thread adapter.
This stainless barrel thread adapter easily attaches to the factory-finished plain muzzle using two set screws. You can install it yourself in minutes, and remove it just as quickly.
Based on precise measurements of your rifle’s barrel at the muzzle and 1 inch back—which you provide after ordering—we can custom machine this barrel thread adapter to match your barrel’s diameter.
