Aac Mk13-sd Mb 90t 762mm 1/2-28

The AAC MK13-SD MB 90T 7.62mm muzzle brake is a precision-engineered suppressor accessory built for tactical operators and precision shooters who demand versatility in sound mitigation and recoil management. This Advanced Armament Corp design represents decades of suppressor integration experience, serving military, law enforcement, and civilian precision rifle platforms where modularity and performance converge. The MK13-SD platform addresses the critical need for effective sound signature reduction without sacrificing the ergonomic or ballistic characteristics that define professional-grade rifle systems.

Built around AAC's proven MK13 suppressor core, this 90-tooth configuration optimizes internal geometry for controlled expansion and efficient sound attenuation across the 7.62×51mm NATO/.308 Winchester spectrum. The 1/2x28 threaded interface ensures compatibility with standard large-bore rifle platforms, while the integrated muzzle brake design reduces felt recoil and muzzle rise—critical factors in sustained fire accuracy and shooter control. Weighing just 0.31 pounds, the compact 4-inch overall length minimizes sight line obstruction and profile extension, allowing integration into both short-barrel systems and precision rifle builds without compromising weapon handling or tactical mobility.

Professional operators deploying precision 7.62mm systems benefit most from this accessory, including special operations teams, designated marksmen, and long-range competition shooters. Installation is straightforward—simply hand-tighten or use a suppressor wrench onto any 1/2x28 rifle muzzle, ensuring proper seating against the target shoulder. Verify zero after installation, as muzzle device attachment can shift point of impact; professional gunsmiths recommend checking head-space and ensuring the barrel shoulder is clean before final assembly. This component integrates seamlessly with standard AAC suppressor mounts and fire control systems.
