AAC Blackout Features The Blackout flash hider is engineered specifically for suppressed use featuring a precision taper interface that delivers a repeatable rock-solid lockup every time a compatible AAC suppressor is attached. The 1x16 Left-Hand Threaded Tapered Mount is purpose-designed to engage AAC suppressors with the same taper mount system eliminating rattle and ensuring consistent alignment on .223 Rem/5.56 NATO hosts. This taper interface is a defining characteristic of AAC s mounting philosophy providing a level of mechanical precision that direct thread alone cannot match. Installation is straightforward on any .223 Rem/5.56 NATO rifle with a standard 1/2x28 threaded muzzle making the Blackout a natural first step for shooters building out an AAC-compatible suppressed host. The black finish provides a clean low-visibility profile that blends with standard carbine aesthetics while holding up to the heat and carbon exposure of suppressed fire. Whether used as a standalone flash hider or as a mounting platform for an AAC taper mount suppressor the Blackout delivers the fit and function that AAC shooters expect.
