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.
The 18-Tooth Blackout flash hider makes use of AAC's original spring mount sound suppressor mounting system. The 18T mount is a simple and secure way to quickly attach or detach an AAC silencer via a single inconel spring in the base of the silencer body. 18-T models are designed specifically for use with AAC's first generation, fast attach silencers, and are not compatible with the newer ratchet mount (51-Tooth) or ratchet mount taper (90-Tooth) sound suppressors. Adds 1.875" to the barrel and utilized the 18T spring mount. Torque wrench is need for installation - approximately 20-30ft.-lbs.
Compatible with AAC M4-1000, SCAR-SD, and Pre-2007 M4-2000
