MD:9 CQB – 908 SBR
The Maxim Defense MD:9 CQB – 908 SBR delivers full-size AR-9 performance in a compact, suppressor-ready short barrel rifle platform built for duty. Featuring an 8.5” free-floating barrel, Gen:7 CQB stock, and our patented Roller Delayed Blowback (RDB) system, the MD:9 CQB SBR offers smooth cycling, reduced recoil, and enhanced accuracy in close-quarters and high-tempo environments. Outfitted with top-tier components—including a Radian charging handle and safety selector, ALG Combat trigger, Maxim pistol grip, and ambidextrous magazine release—this rifle is built to dominate at the professional level.
The included Maxim Defense Hatebrake™ redirects blast and gas forward, improving comfort and control during rapid fire—especially indoors or in tight spaces. Suppressor-ready and purpose-built for hard use, the MD:908 SBR pairs seamlessly with the MS9 Suppressor, offering a rugged solution with minimal back pressure and outstanding reliability.
