The HUB2K is a spin on the legendary M4-2000. With the new DMLS 3D printing, AAC was able to make the can stronger and lighter without giving sound performance up. Now with oversized baffles to help eliminate some backpressure and also with minimizing end cap strikes on SBRs, the HUB2K is the new chapter in the legacy of the M4-2000. With HUB standard 1.375-24 in the rear, you can run any HUB style mount and still have that legendary performance the M4-2000 was known for.
