Our famous ATRS Gill brake is now available for the Steyr HS 50 rifles. The most efficient muzzle brake for use on large caliber rifles and was designed specifically for prone shooting to control dust signature. Our Gill brakes have been engineered to reduce the felt recoil by 50% and to help with muzzle control so you are able to remain on target much better. Our Gill brakes do not direct the muzzle blast at the shooter like the factory Steyr brakes. These brakes employ the factory Steyr lock ring for easy install. These brakes are machined from 17-4 stainless steel and have been salt bath nitrided for an extremely durable matte black finish.
