The Dead Air Keymo muzzle brake brings modular suppressor mounting to your rifle setup. Built on Dead Air Armament's proven Keymo quick-detach interface, this brake threads directly onto your barrel and provides a solid anchor point for any Keymo-compatible suppressor. If you run multiple suppressors across different firearms or want to swap between hearing protection and a bare muzzle device without tools, the Keymo system simplifies the process — and this brake delivers the foundation that makes it work.
Dead Air engineered the Keymo platform for repeatability and zero shift. Suppressors lock on and come off consistently, so you won't lose your point of impact when swapping gear at the range or in the field. The brake itself is a no-frills component: it's machined to tight tolerances and designed to interface cleanly with Keymo suppressors while serving as a standard muzzle device when running naked.
This model is sized for .46-caliber and .578-28 thread pitch barrels—common specs for magnum and large-bore rifles. Verify your barrel's thread pattern before ordering; Keymo brakes are application-specific and won't fit standard 5/8-24, 1/2-28, or other common threads. If you already own Dead Air suppressors with the Keymo mount, or you're building out a suppressor collection and want standardized quick-detach across your guns, this brake is the starting point.

| Mount Type | Keymo Quick-Detach |
| Caliber / Size | .46-caliber |
| Thread Pitch | .578-28 |
Any suppressor equipped with Dead Air's Keymo quick-detach mount will attach to this brake. Keymo is Dead Air's proprietary modular system, so compatibility is limited to their suppressor line and other manufacturers who license the interface. Check your suppressor's specs to confirm it has a Keymo mount.
This brake is threaded for .578-28 barrels and is sized for .46-caliber. You must verify your barrel's thread pitch and diameter before purchasing. Keymo muzzle brakes are caliber and thread-specific; ordering the wrong size will not fit your gun.
No. The Keymo brake functions as a standard muzzle device on its own. The quick-detach interface is there if and when you want to mount a Keymo suppressor, but the brake works fine as a standalone component.
This is a muzzle brake designed around the Keymo interface. It is not a flash hider. For detailed performance characteristics, consult Dead Air Armament's published specifications or contact us directly.
