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.
