AAC Suppressors & Mounts

SUPPRESSORS AND QUICK-DETACH SYSTEMS

Advanced Armament Corp (AAC) pioneered quick-detach suppressor systems and remains a key player in the NFA market. Their current lineup includes the new 300 SD, specifically designed for 300 Blackout, the reimagined 762-SDN-6, and the new M4-2000. Capitol Armory stocks AAC's legacy 51T and 90T mounting systems, including flash hiders, muzzle brakes, and compensators. The 51T system remains popular for older AAC suppressors, while the 90T serves their newer rifle cans.  AAC's newest mounting system is HUB compatible and features a smooth M16x1LH tapered mount.  

All of AAC's mounting systems provide fast attachment and removal across multiple host firearms. AAC's pistons fit their pistol suppressors for tilting-barrel handguns. We maintain inventory of AAC mounts and accessories to support existing AAC suppressor owners alongside current production models.

All AAC suppressor purchases include expert electronic NFA filing and direct-to-door delivery.
