The Dead Air KeyMicro Brake DA115 is a compact 1/2-28 threaded flash hider built for shooters who want effective muzzle control without the bulk. This short, lightweight muzzle device works as a standalone flash hider or pairs with Dead Air's KeyMicro Adapter to create a suppressor mounting platform. If you're running a rifle or pistol platform where real estate and weight matter—whether you're working a precision rifle, a home-defense carbine, or a competition build—the KeyMicro delivers the same proven technology that made Dead Air's industry-standard KeyMo system a go-to choice for serious shooters.
The KeyMicro platform is designed around modularity and simplicity. The flash hider uses the same quick-change technology as the KeyMo system, so if you invest in KeyMicro suppressors down the road, this brake becomes a permanent fixture on your barrel—swap cans in seconds without tools or re-zeroing. The 4140 heat-treated steel construction with black nitride finish means it'll stand up to hard use and corrosive environments without compromising looks or function.
This specific model threads at 1/2-28 and is bored for centerfire rifle cartridges. The compact 2-inch length keeps your overall profile manageable on shorter barrels or tight setups where every fraction of an inch counts. Whether you're planning to run it bare or as the foundation of a suppressor platform, the KeyMicro Brake offers practical, no-nonsense flash management for hunters, long-range competitors, and tactical shooters alike.

Frequently Asked Questions
Will the KeyMicro Brake work with Dead Air suppressors?
The KeyMicro Brake is compatible with Dead Air KeyMicro and KeyMo suppressor systems when paired with the appropriate KeyMicro Adapter. It functions as a flash hider on its own or as the mounting base for compatible suppressors.
What calibers and barrel threads does this fit?
This model is threaded 1/2-28 and bored for .30 caliber (centerfire rifle) applications. If you need a different thread pitch or caliber bore, Dead Air makes KeyMicro variants in other common configurations.
Can I use the KeyMicro Brake without a suppressor?
Yes. The KeyMicro Brake functions as an effective standalone flash hider. It's designed to work minimally on its own and becomes part of a larger suppressor platform when you add a compatible Dead Air can and adapter.
How does the KeyMicro system compare to other quick-change muzzle devices?
The KeyMicro uses the same proven quick-change technology as Dead Air's KeyMo system, allowing tool-free, zero-shift suppressor mounting and removal. The compact design and modular approach make it a practical choice for shooters who want flexibility without the weight and length of traditional fixed muzzle brakes.
