The AAC BlackOut 51T Flash Hider is a proven flash suppression solution designed to dramatically reduce muzzle flash, even on short-barreled rifles. Its open-end, three-prong design offers greater strength than four-prong units while resisting the wear and erosion common to closed-end flash hiders.

Precision machined from high-strength aerospace steel and finished with AAC’s durable, corrosion-resistant SCARmor coating, it is built for hard use. Featuring the 51T ratchet mount interface, this flash hider allows fast, secure suppressor attachment in seconds with compatible AAC suppressors, delivering reliable performance and seamless integration.
