AAC Blackout 51T 5.56mm 1/2″-28 Thread
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.
