AAC HUB2K

The AAC HUB2K is a modern evolution of the renowned M4-2000 suppressor, integrating advanced 3D printing technology to enhance strength and reduce weight while improving sound performance. Crafted from DMLS 718 Inconel, this suppressor features oversized 6mm baffles designed to minimize backpressure and ensure concentricity. These baffles allow you to run the HUB2K on your 5.56 and 6ARC rifles, and the reduced backpressure will keep your rifles running reliably, even when shooting short-barreled rifles (SBRs). The HUB2K is equipped with HUB standard 1.375-24 threads, ensuring compatibility with a wide range of HUB-style mounts, and is rated for full-auto use, delivering the robust performance that the M4-2000 was known for.

The AAC HUB2K delivers cutting-edge performance with its advanced 3D-printed DMLS 718 Inconel construction, ensuring unmatched strength and reduced weight. Its oversized 6mm baffles minimize backpressure, allowing for reliable operation on both 5.56 and 6ARC rifles, including SBRs. Featuring HUB standard 1.375-24 threads, the HUB2K offers seamless compatibility with a wide range of mounts, while its full-auto rating ensures durability under demanding use.
