Dead Air DA117 KeyMicro 9mm Flash Hider M13.5x1 LH Black Nitride

The Dead Air DA117 KeyMicro is a compact 9mm flash hider designed to tame muzzle flash on pistol-caliber hosts while doubling as the dedicated mounting interface for the Dead Air KeyMicro suppressor system. Machined from 4140 HT alloy steel and finished in a low-glare Black Nitride, this short, lightweight muzzle device keeps added weight and length to a minimum on short-barrel PCC and pistol platforms.

This version is threaded M13.5x1 LH, the factory SIG MPX and compatible 9mm pattern, making it a direct-fit upgrade for the OEM muzzle hardware on MPX-family firearms and other pistol-caliber hosts cut to that pitch. The KeyMicro flash hider runs as a stand-alone unit to reduce flash signature, or pairs with the Dead Air DA451 KeyMicro adapter to mount the company's micro 9mm suppressor in seconds without tools.

Specs include an overall length of 2.063" and a weight of approximately 3.36 - 3.52 oz. Like every KeyMicro muzzle device, the DA117 is engineered for repeatable concentric alignment so shooters switching between unsuppressed and suppressed fire get consistent point of impact and clean lockup with every installation.
