This 90-Tooth Blackout flash hider works in conjunction with AAC's ratchet taper mount silencers, an evolutionary step forward from the original 51-Tooth ratchet mount design. The new 90T gear on the flash hider interfaces with a spring biased ratchet lever on the suppressor to eliminate the potential for the silencer to inadvertently unthread during firing. The flash hider's finer pitch external ACME thread and improved low angle body taper snug it up securely with the correspondingly angled surface inside the silencer, creating a rock solid platform. Not compatible with the older spring mount (18-Tooth) or ratchet mount (51-Tooth) sound suppressors.
