Advanced Armament Corp Aac 51T Pingless Flash Hider 1/2x28 13.7in

The Advanced Armament Corp AAC BlackOut Flash Hider for 51T mounts delivers an extremely efficient muzzle control, effectively eliminating flash even on short barrels, with a pingless design that remains robust once torqued to the correct specification. Engineered to fit most 13.7/13.9 inch barrels to achieve a 16" overall length, these units require careful verification before pinned and welded to reach total length, and all NFA rules apply. Constructed from high-strength aerospace steel alloy and finished with a durable SCARmor coating, the BlackOut flash hider blends strength with corrosion resistance while maintaining dependable performance under demanding conditions. The open-end, 3-prong design—stronger in its class than 4-prong configurations—reduces wear and erosion associated with closed-end models, promoting longevity and consistent flash reduction. Each unit is machined with a pre-drilled pilot hole for straightforward installation of a pinned and weld setup, enhancing fieldable practicality. Key attributes include a 5.56mm 1/2x28 thread pattern, included Rocksett for reliable retention, and a purpose-driven 51T mount compatibility, all contributing to a reliable, quiet, and feature-rich muzzle device that supports precise shooting dynamics in a variety of rifle configurations.
