The Dead Air KeyMo 46 Muzzle Brake is a quick-detach muzzle brake for big-bore rifles, providing efficient braking for calibers up to .458. It's part of Dead Air's KeyMo system, and it's compatible with all Dead Air suppressors equipped with a KeyMo adapter. The KeyMo adapter is sold separately. Dead Air says the suppressor removes easily without carbon locking onto the mount.
The KeyMo 46 seats on the muzzle, so it works on rifle barrels with little to no shoulder and doesn't need shims. Dead Air says the brake ports are designed to distribute gas and pressure efficiently inside the suppressor. It's machined from 4140 heat-treated chromium-molybdenum steel with a black nitride finish, and the overall length is 2.58". It comes in four thread options, so choose the one that matches your barrel. Check your suppressor's caliber limits before mounting the KeyMo 46 on your rifle.
