KeyMo Muzzle Brake

Buy KeyMo Muzzle Brake | Features & Overview

The full size KeyMo Muzzle Brake was built for shooters who run their rifles hard and expect a mounting system that performs.

It’s a purpose-built interface for the KeyMo mounting system, combining aggressive recoil reduction with one of the most proven suppressor attachment systems on the market. The multi-port design keeps the rifle flat under recoil and fast on follow-up shots, while the precision-machined taper interface ensures consistent lockup and repeatable return to zero every time you mount your suppressor.

The KeyMo system uses a taper design with a mechanical detent that resists loosening under heat and vibration. This full size brake is especially at home on higher-pressure calibers and shorter barrels where recoil impulse and precision matter most.

Whether you’re running duty rifles, hard-use training guns, long-range setups, or any combo of purpose-built rifles, the KeyMo Muzzle Brake delivers consistency, durability, and control where it counts.

NOTE: The DA101 and DA102 come with a pre-drilled hole for pin & weld at the 6 O’clock position. The DA103, DA104, and DA106 do not have a pin/weld hole and do not have the three port holes on the top wrench flat.

KeyMo Brakes come with an included shim kit and instructions for timing your muzzle device.
