Availability: In Stock
The Dead Air Keymicro Brake DA120 is a compact flash hider engineered for shooters who demand a lightweight muzzle solution without the bulk. Built from 4140 heat-treated alloy steel and finished in durable black nitride, this 5/8x24 Sig Taper threaded device measures just over 2 inches long and weighs between 3.36 and 3.52 ounces—making it an ideal choice for modern sporting rifles, short-barreled platforms, and precision setups where barrel length and weight matter. Whether you're running a dedicated suppressor host or prefer to go unsuppressed, the Keymicro works as a standalone flash hider while also pairing seamlessly with Dead Air's KeyMicro Adapter to unlock compatibility with the industry-proven KeyMo mounting system.
Dead Air's design philosophy centers on modularity and reliability, and the Keymicro Brake reflects that commitment. The same proven technology that made the KeyMo system a standard across competitive shooters and hunters carries into this minimalist package. Thread it directly onto your 5/8x24 Sig Taper barrel for immediate flash reduction, or integrate it into a suppressor-ready setup by adding the compatible KeyMicro Adapter. This flexibility means you're not locked into a single configuration—your muzzle device can evolve with your rifle's mission.
The through-bore is optimized for .30 caliber ammunition, giving you clearance for centerfire rifle rounds while maintaining the compact profile that makes short-barreled rifles practical. If you're building or upgrading a precision rifle, short-barrel hunting rig, or AR pistol setup, the Keymicro Brake offers the Dead Air engineering you trust in a form factor that doesn't waste an inch of real estate.
