AAC Blackout Flash Hider - 5.56mm - 90T SR Series Only - 1/2-28 - 64242

The AAC BlackOut Flash Hider 90T SR Series for 5.56mm 1/2-28 is a high-performance muzzle device from Advanced Armament Company that combines aggressive efficiency with durable engineering to suppress muzzle flash even on short barrels. Its open-end three-prong design is inherently stronger than four-prong units and resists wear and erosion better than closed-end styles, delivering reliable performance under demanding conditions. Crafted from high-strength aerospace steel and finished with the SCARmor coating for lasting corrosion resistance, this flash suppressor pairs rugged construction with consistent, effective flash reduction. The inclusion of Rocksett enhances barrel accuracy by stabilizing the muzzle device under rapid firing, making it a practical choice for both tactical and precision-oriented applications. Designed to integrate seamlessly with 1/2-28 threaded muzzles, the AAC BlackOut SR Series adds a low-profile, functional aesthetic to modern rifles while helping shooters maintain situational awareness and control in low-light environments. Whether sprinting through dynamic field scenarios or fine-tuning a match rifle, this flash hider delivers dependable performance, proven AAC engineering, and a professional-grade finish.
