Dead Air DA161 KeyMo Muzzle Brake 5/8x24 Thread .45 Cal

The Dead Air DA161 KeyMo Muzzle Brake transforms recoil management for .45 caliber firearms while providing seamless suppressor mounting capability. This precision-machined brake reduces felt recoil and muzzle rise significantly compared to standard flash hiders or bare muzzle threads.

What Makes This Different

The KeyMo mounting system sets this brake apart from traditional thread-on suppressors with its quarter-turn attachment mechanism. Dead Air's proprietary taper mount design ensures consistent lockup and eliminates the need for shims or timing devices. The brake features aggressive side ports that redirect gases to counteract muzzle climb, while the front-facing ports minimize blast directed toward the shooter.
