'74 Style Brake for Saiga-410

This '74 style muzzle brake is threaded to M15x0.75LH to fit the factory threads on the 410 shotgun barrels. They are marked "U.S.A." or "Made In USA" and count as a compliance part. They are designed to work with all loads from slugs to shot.

I recommend wrapping the barrel threads with teflon tape to index the brake. It's cheap and isn't affected by heat from normal firing.
