Quickly and easily convert your 5/8″ diameter, non-threaded barrel to 1/2-28 threads so you can attach muzzle brakes and other end-of-barrel accessories.

IF your barrel measures .625 inch (15.875 mm)

Please verify with precision metal calipers or micrometer before you order.
If it’s a different size, you need to order one of our custom fit adapters.

Please use quality metal calipers or micrometer to ensure the diameter.

No machining required! And less expensive than going to a machinist or gunsmith to thread your barrel.
