Not all muzzle devices are created the same. There aren’t many muzzle brakes and compensators that ‘understand’ proper high-pressure gas dynamics. This AR-15/AR10 Muzzle Brake has a three chamber design that significantly reduces muzzle rise. It has 5/8×24 threads, so you can attach it to your favorite .308 or 300 blackout barrel and finally finish that build you have been working on. It is made from high-quality steel and features a durable phosphate finish that will look great on any AR build.
