The Dead Air KeyMount Muzzle Brake for .338-caliber rifles, threaded 3/4×24 (brand part no. DA103), is a recoil-reducing muzzle device built for Dead Air Silencers‘s KeyMount suppressor interface. It gives a .338-class rifle a functional brake for unsuppressed shooting while doubling as the mounting platform the moment a KeyMount-compatible Dead Air suppressor is attached. Since it stays on the rifle full time, the point of impact holds steady whether or not the suppressor is mounted. It ships as a standalone muzzle device, separate from any suppressor.
