Maximize Shooting Experience with a CMMG Muzzle Brake

The CMMG AR-10 Zeroed Muzzle Brake is the perfect muzzle device for AR-10 builds chambered in .308 Win and 7.62x39mm. This muzzle brake features angled ports that provide excellent recoil control and effectively minimized muzzle rise when firing.

This results in an excellent return to target acquisition for the shooters giving them more accurate follow-up shots.

Modern 2-Chamber Design

The CMMG ZEROED Muzzle Brake is made from 4140 Steel with a Nitride finish to ensure maximum durability as well as corrosion resistance for long-term use.

It also utilizes a new aggressive chamber design that improves gas flow and reduces felt recoil significantly.  The 2-chamber design looks great on any standard profile barrel while effectively eliminating recoil leaving your rifle shooting flat and soft.

All CMMG products come with our Lifetime Quality Guarantee.
