The Maxim Defense CQB MXM-47575 G6 buttstock assembly is a purpose-built rear support component for shooters running Maxim's compact tactical rifles and PDW platforms. If you're building or upgrading a CQB Gen 6 or compatible PDW brace system, this assembly handles the ergonomic side of the equation—the part that meets your shoulder. B-stock pricing reflects minor cosmetic marks or packaging differences; the function and fit are full-spec.
This is a buttstock assembly only, meaning you're getting the rear end component without the complete rifle or primary brace housing. That makes it ideal for builders who already have a barreled upper or core platform and need a matching rear module, or for shooters looking to swap out or upgrade their existing setup. Maxim's CQB line focuses on close-quarters work and shorter sight radiuses, so this assembly pairs with that philosophy—compact, manageable, and built for realistic defensive or tactical scenarios.
Black anodizing keeps it tough and professional looking. Compatibility is locked to CQB Gen 6 and PDW brace systems, so verify your platform before ordering. If you're deep in the short-rifle rabbit hole, Maxim's ecosystem gives you modular peace of mind.
