Dead Air
The Dead Air KeyMo Micro Brake is a compact, lightweight muzzle brake built for shooters who want recoil management without bulk. Threaded 1/2x28, this minimalist brake delivers effective single-port design on platforms ranging from 9mm pistol-caliber rifles to precision rifle builds. Whether you're running it standalone or pairing it with a KeyMo or KeyMicro Adapter for a complete suppressor-ready mounting platform, the Micro Brake gives you versatility in a package that won't make your gun front-heavy or unwieldy.
Dead Air engineered the KeyMicro line with the same proven technology behind their industry-leading KeyMo system. That means solid engineering, reliable repeatability, and compatibility across a growing ecosystem of muzzle devices and suppressors. At just over 3 ounces and measuring 2 inches in length, the Micro Brake stays out of the way while you work. The 4140 heat-treated steel body with black nitride finish resists corrosion and stands up to hard use, whether you're shooting suppressed or unsuppressed.
This is a practical choice for shooters who care about keeping their setup lean and functional—no marketing nonsense, just a solid brake that threads on, works, and plays well with modern suppressor infrastructure. If you already own Dead Air suppressors or are building around the KeyMo/KeyMicro platform, the Micro Brake fills a real gap in the lineup.
| Thread Pitch | 1/2x28 |
| Material | 4140 HT Alloy Steel |
| Finish | Black Nitride |
| Weight | 3.41 oz |
| Length | 2.063" |
| Bore Diameter | 9mm |
| Pin & Weld Ready | Not pre-drilled |
The Micro Brake itself is a standalone brake. However, it is compatible with Dead Air KeyMo and KeyMicro Adapters, which allow you to build a complete suppressor-mounting platform. Check your suppressor's quick-detach system to confirm compatibility.
The 1/2x28 thread pitch is standard for 9mm platforms, including 9mm rifles, pistol-caliber carbines, and some rifle applications. The 9mm bore accommodates high-velocity rifle rounds as well. Verify thread pitch compatibility with your barrel before purchase.
Yes, the Micro Brake is pin-and-weld capable, though it does not come pre-drilled. You'll need to have a gunsmith drill and pin it if you choose that route.
The KeyMicro line uses the same core technology as the KeyMo system and shares compatibility with KeyMo adapters, offering modularity and reliability in a lighter, more compact footprint.
