AAC Blackout Flash Hider 5.56mm 90T - 1/2-28 SR Series Only

The AAC Blackout Flash Hider 5.56mm 90T is a precision muzzle device engineered for shooters and tactical professionals who demand flash signature reduction without sacrificing reliability. Designed exclusively for the SR Series platform, this flash hider addresses a critical operational need: minimizing visible muzzle flash during low-light engagements, training scenarios, and tactical operations where shooter visibility must be preserved.

Built by Advanced Armament Company—a manufacturer with deep roots in suppressor and muzzle device innovation—this accessory utilizes a 90-tooth design that functions by redirecting and cooling burning propellant gases away from the shooter's line of sight, effectively reducing the incandescent cloud visible to the naked eye. Its 1/2-28 threaded interface ensures compatibility with standard AR-15 and 5.56mm barrels, while the compact length of 3.75 inches minimizes added sight radius shift and maintains the rifle's handling characteristics.

Weighing only 0.35 pounds, the AAC Blackout Flash Hider adds negligible mass to the muzzle, preserving barrel harmonics and accuracy potential—critical factors for precision-focused operators and competitive shooters who depend on consistent performance. This muzzle device is ideal for law enforcement tactical teams, military personnel, and civilian shooters conducting night-fire exercises.
