Bergara ST1 Muzzle Brake .30 Cal 5/8-24

The Bergara ST1 is a self-timing muzzle brake engineered for .30-caliber rifles. Its angled baffle design applies downward pressure without venting gas into the line of sight or increasing ground disturbance. The result is a measurable reduction in felt recoil along with minimal muzzle rise. Built for durability, the brake is offered with a nitride finish over 17-4 grade stainless steel and fits barrels with standard 5/8-24 threads.
