Description

The Sinister is and excellent performer on 300wm and smaller rifles. With the ports facing upwards at 5 degrees it keeps the muzzle planted and cuts the recoil down. Our brake has 25% more port volume compared to similar items for added recoil reduction and we use the popular locking nut so anyone can time their own item without having to pay a gunsmith. Thread size is 5/8"x24tpi class 3b
