Dead Air DA120 KeyMicro Brake Flash Hider 5/8x24 SIG Taper 9mm Black Nitride

The Dead Air DA120 KeyMicro Brake Flash Hider is a compact, purpose-built muzzle device for 9mm Luger pistol-caliber carbines and subguns. Machined from 4140 HT Alloy Steel and finished in a corrosion-resistant Black Nitride coating, it tames muzzle flash while doubling as the locking interface for Dead Air's KeyMicro suppressor mounting system.

This DA120 variant is threaded 5/8"-24 SIG Taper, making it a direct fit for SIG-pattern pistol-caliber carbine barrels. It measures 2.06" overall and tips the scales at just 3.36 to 3.52 oz, adding minimal weight and length to the host firearm. The KeyMicro Brake uses Dead Air's cam-lock geometry to deliver a repeatable, rock-solid lockup with compatible Dead Air KeyMicro-equipped suppressors, while also functioning as a capable stand-alone flash hider when running unsuppressed.

Whether running a 9mm PCC in competition, training, or general range use, the DA120 KeyMicro Brake brings Dead Air's reputation for precision-engineered, hard-use muzzle devices to the platform.
