Advanced Armament Corp 51T Flash Hider 7.62x51 5/8-24 Pingless PWB Mount

The AAC Advanced Armament Corp BlackOut Flash Hider for 51T mounts is an extremely efficient design that effectively eliminates muzzle flash, even on short barrels, with a pingless configuration once torqued to the correct specification, allowing most 13.7/13.9 inch barrels to reach a 16" overall length when pinned and welded—note to double check before final installation. Machined from high strength aerospace steel and finished with a hard, corrosion resistant SCARmor coating, this open-end, 3-prong flash hider is inherently stronger than 4-prong designs and is less susceptible to the wear and erosion common with closed-end units, delivering reliable performance in demanding conditions. The unit is precisely engineered for 7.62mm and 5/8x24 threading on 51T mount barrels, and includes Rocksett for effective mounting and muzzle control. With a pre-drilled pilot hole for straightforward pinned-and-weld installation, this component supports versatile rifle configurations while maintaining robust durability and consistent flash suppression across a range of barrel lengths and gas settings. A trusted choice for shooters seeking enhanced signature reduction, improved control, and durable, field-ready construction.
