Key-Micro Brake

The Dead Air Armament Key-Micro Brake is available now from LM Ironwerks, a licensed FFL/SOT dealer in Louisville, Kentucky.

The KeyMicro Brake is a short, lightweight single port muzzle brake suited for a variety of platforms. Designed for use with our KeyMicro Adapter, it functions as a minimalist brake on its own. Pair them together for the ultimate mounting platform. This is the same technology found in our industry-best KeyMo system. The KeyMicro muzzle devices are also compatible with our KeyMo Adapter.

KeyMicro muzzle devices feature a 9mm Bore.

What It Does

A muzzle brake redirects propellant gas out to the sides to reduce felt recoil and muzzle rise, so you can stay on target and get faster follow-up shots. On suppressor-ready designs it also serves as the mounting point for the suppressor. Brakes are loud for people standing beside the shooter, so they are often paired with a suppressor.

Before You Order

Match the thread pitch to your barrel (1/2×28 is common on 5.56 and .22 rifles, 5/8×24 on .30 caliber rifles) and confirm the device is made for your suppressor’s mounting system. Muzzle devices should be installed, timed and secured exactly as the manufacturer specifies. If you’re not sure, have a gunsmith do it.
