The Dead Air KeyMicro Brake DA116 is a compact muzzle device built for shooters who want serious mounting versatility without the bulk. Threaded in 5/8x24, this minimalist brake pairs with Dead Air's KeyMicro Adapter to create a quick-detach platform for suppressors—or stands alone as a flash-reducing muzzle brake on rifles and pistols where space is tight. It's built on the same proven quick-attach technology that powers Dead Air's industry-standard KeyMo system, so if you're already invested in that ecosystem, the KeyMicro brake offers another way to stay compatible.
Machined from 4140 heat-treated alloy steel and finished in tough black nitride, this device is engineered to handle centerfire rifle and pistol use without compromise. At just over 2 inches long and weighing between 3.36 and 3.52 ounces, it won't add noticeable length or heft to your gun. The design keeps your sight picture and ergonomics intact, making it ideal for hunting rifles, tactical builds, or any setup where keeping the profile compact matters. Whether you're planning to run it permanently as a brake or use it as a quick-swap adapter base for a suppressor, the KeyMicro brake delivers Dead Air's reputation for precision engineering in a size that actually fits modern firearms.
The KeyMicro platform gives you real flexibility: use the brake on its own, thread on a KeyMicro Adapter to mount a suppressor, or swap adapters to match different suppressors in your collection. It's that modular thinking applied to muzzle devices—no proprietary lock-in, just solid engineering that works across multiple platforms.

Frequently Asked Questions
What suppressors work with the KeyMicro Brake DA116?
The DA116 is designed as a mounting platform for Dead Air KeyMicro Adapters. When paired with a KeyMicro Adapter, it accepts Dead Air suppressors engineered for that quick-detach system. The brake itself is also compatible with Dead Air's KeyMo Adapter, expanding your suppressor compatibility within the Dead Air ecosystem.
Can I use this brake without an adapter?
Yes. The KeyMicro brake functions as a standalone muzzle device with flash-reduction properties, so you can thread it directly onto a 5/8x24 barrel and shoot without an adapter or suppressor.
What calibers does the 5/8x24 version support?
The DA116 in 5/8x24 is rated for both 9mm and .30 caliber (including centerfire rifle and magnum rifle applications), depending on the through-bore configuration and adapter pairing. Verify bore diameter compatibility with your specific suppressor if using an adapter.
How much does it add to barrel length?
The KeyMicro brake is 2.063 inches long, so it will extend your barrel by just over 2 inches—minimal for a multi-use muzzle device platform.
