AAC BlackOut Flash Hider for 90TV \- No-Ping 3-Prong Flash Hider Optimized for Short Barrels The AAC BlackOut Flash Hider for 90TV mounts is a purpose-built muzzle device that suppresses visible flash even on short barrels while providing a durable, serviceable QD attachment interface. Machined from high-strength aerospace steel alloy and finished in corrosion-resistant SCARmor, the BlackOut combines corrosion and erosion resistance with tight tolerances for repeatable engagement and long service life. A three-prong, open-end geometry delivers a no-ping acoustic signature and inherent structural strength that resists the wear and erosion commonly seen with closed-end designs. The 90TV BlackOut also integrates three points of retention for the QD adapter and uses a forward taper ahead of the mounting threads to support positive lockup and easy, reliable indexing. Engineered for short-barrel applications, porting and mass distribution are tuned to minimize flash while preserving predictable muzzle behavior and suppressor longevity when used with compatible QD mounts. Intended for use on 90TV-compatible mounting systems, the BlackOut offers a compact, rugged option for shooters who require low-flash performance and a robust quick-attach interface in demanding environments. Verify mount fit and visually confirm baffle alignment after installation before firing.
