AAC NSN MARKED M4-2000

The AAC M4-2000 Mod 08 is a battle-tested 5.56mm suppressor with a National Stock Number (NSN) to prove its military pedigree. Featuring AAC’s 51T Ratchet-Mount system, it attaches quickly to compatible BLACKOUT and BRAKEOUT muzzle devices (not included) with rock-solid lockup and minimal POI shift.

Built from fusion-welded aerospace alloys, it’s full-auto rated and optimized for barrels as short as 10 inches. A tapered bore ensures precision alignment, while the internal design reduces back pressure, blowback, and cyclic rate—making it as comfortable to shoot as it is durable.
