The Dead Air Keymo muzzle brake is a precision-engineered muzzle device designed for shooters who run Dead Air suppressors and want quick-disconnect convenience without sacrificing brake performance. This .46 caliber brake in 5/8-32 thread pitch delivers the signature Keymo interface—Dead Air's proprietary fast-attach system that locks your suppressor on solid and comes off in seconds. If you're running suppressed rifle setups and want the ability to shoot unsuppressed with a quality brake attached, the Keymo brake bridges that gap cleanly.
Built for serious shooters and hunters who value modularity, the Keymo system eliminates the need for multiple brake profiles or adapters. Thread it on, mount your compatible Dead Air suppressor, and you've got a locked-and-loaded connection. The .46 bore and 5/8-32 thread specification fit a range of centerfire rifle applications, though always verify your barrel's thread pitch and caliber before ordering—getting this detail right matters.
Whether you're building a precision rifle for the range, a hunting setup where you toggle between suppressed and unsuppressed shots, or a defensive rifle that benefits from both brake performance and suppressor modularity, the Keymo system keeps things simple and reliable. Dead Air's reputation for rock-solid suppressor attachment translates directly to brake confidence.
