This AAC Blackout AR-15 Flash Hider is an extremely efficient design that effectively eliminates muzzle flash, even on short barrels. The open-end, 3-prong design of the Blackout is inherently stronger than 4-prong units, and is not subject to the wear and erosion commonly encountered with closed-end designs. All Blackout flash suppressors are machined from high strength aerospace steel alloy and coated in a hard, durable, corrosion resistant SCARmor finish.
This 51T Blackout flash hider works in conjunction with AAC's improved ratchet mount sound suppressors. The 51-T mount is an intuitive, lightning fast silencer attachment/detachment system that allows for secure installation of a suppressor in less than 3 seconds with no tools or moving parts. Not compatible with the older spring mount (18-Tooth) or newer ratchet taper mount (90-Tooth) sound suppressors. Adds 1.875" to the barrel and utilized the 51T Rachet Mount. Torque wrench is need for installation - approximately 20-30ft.-lbs.
Compatible with AAC ACR-SD, 416-SD, 249-SD, Post-2007 M4-2000, Mini 4, Post-Mid 2010 7.62-SD, 7.62-SDN6, and Mini 7
