Compact AR-9 style pistol chambered in 9mm with a free-floating barrel and M-Slot-compatible handguard. Finished in nitride and Type III anodizing and offered with a CQB brace.
The Maxim Defense MD9 CQB is an AR-9 style pistol engineered to meet demand for compact, carbine-pattern 9mm platforms. Manufacturer materials describe a free-floating barrel and a custom handguard that creates a monolithic-like upper receiver platform with M-Slot compatibility. The MD9 is finished in nitride and Type III anodizing and is offered with a CQB brace for compact carriage.
For an optic under $1,000 that complements this platform, a compact red dot such as the Vortex Venom (6 MOA) pairs well with the MD9’s compact sight radius and modern handguard mounting options. Typical applications include range training and competitor-style carbine matches where a compact, controllable 9mm platform is desired.
