Dead Air Keymount Muzzle Brake Black, 1/2x28 Threads

The Dead Air Keymount Muzzle Brake in 1/2x28 threads is a precision muzzle device engineered for shooters who want flexibility: run it standalone as a high-performance brake, or use it as the mounting platform for Dead Air's Sandman Series suppressors and KeyMo-equipped cans. The sealed taper design prevents carbon buildup where suppressor meets brake, so you can swap silencers on and off the range without fighting stuck mounts. Built from 4140 HT alloy steel with black nitride finish, it's built to last through thousands of rounds and real-world use.

The 1/2x28 version is sized for .30 caliber rifles—think 5.56 NATO, .308 Winchester, and similar platforms. At 2.82 inches long and under 4.5 ounces, it adds minimal length or weight to your barrel. Whether you're a precision shooter, hunter, or tactical enthusiast, this brake delivers flatter recoil impulse and reduced concussion compared to open-muzzle shooting, while keeping your options open for future suppressor integration.

Dead Air's reputation for engineering robust, modular suppressor systems extends to this brake. The KeyMo mounting interface is fast, reliable, and proven in the field. If you're building a .30 cal rifle now but considering sound reduction later, this brake covers both bases without compromise.
