The AAC Mk13-SD Muzzle Brake 7.62mm 90T 5/8-24 is a precision-engineered muzzle device designed exclusively for suppressed rifle systems. Built by Advanced Armament Company, this brake is mechanically matched to the AAC Mk13-SD and 300-SD suppressors, ensuring optimal sound reduction and recoil management when integrated into a complete suppressor system. The 90T designation indicates the specific bore and threading geometry required for proper indexing and performance.
Machined from aerospace-grade steel alloy and finished with AAC's SCARmor corrosion-resistant coating, this muzzle brake delivers the durability required for sustained tactical operations and harsh field conditions. The 5/8-24 threading accommodates standard 7.62mm rifle barrels across AR10-platform systems, bolt-action precision rifles, and other platform-agnostic setups. At 0.27 lbs, the brake adds minimal weight to the system. Installation includes Rocksett threadlocker and shim kits to ensure proper timing and concentricity—critical factors for suppressor performance and hearing protection efficacy.
This brake is purpose-built for shooters who have committed to the Mk13-SD/300-SD suppressor ecosystem and require OEM-matched components. It is not compatible with other suppressors, making selection straightforward for operators already running AAC suppressed platforms. Serious end-users—military personnel, tactical operators, precision rifle competitors, and law enforcement—rely on matched brake-suppressor combinations to achieve the acoustic and ballistic performance AAC systems are known for.
The 7.62mm/.308 class represents the most common suppressed rifle platform in professional and competitive use. Pairing a quality muzzle brake with a suppressor allows shooters to manage recoil, maintain sight picture during rapid fire, and operate with hearing-safe signature. This AAC brake is a straightforward choice for anyone integrating suppression into a 7.62 system already designed around AAC's proven technology.
