The Dead Air KeyMount Muzzle Brake for .338-caliber rifles, threaded M18x1.5 for Accuracy International barrels (brand part no. DA106), is a recoil-reducing muzzle device built for Dead Air Silencers‘s KeyMount suppressor interface. It’s cut to the metric thread pattern used on Accuracy International rifle barrels, giving those precision rifles a functional brake and a ready mounting point for a KeyMount-compatible suppressor. Since it stays on the rifle full time, point of impact holds steady whether or not the suppressor is mounted. It ships as a standalone muzzle device, separate from any suppressor.
