VFC Maxim Defence MD9-K GBB SMG - Black

VFC Maxim Defense MD9-K GBB SMG - Black

For players who demand ultra-compact maneuverability without sacrificing realistic recoil or weapon handling, the VFC Maxim Defense MD9-K GBB sets a new benchmark for gas blowback Pistol Caliber Carbines (PCC). Fully licensed by Maxim Defense and built on VFC’s high-performing V3 GBB architecture, this AR-9 style submachine gun replicates the real-steel MD9-K down to the smallest detail—delivering violent cycling, crisp trigger response, and maximum adaptability in tight CQB environments.

Why the VFC Maxim Defense MD9-K Rules CQB

• Fully Licensed Maxim Defense Build: Features authentic engraved rollmarks, receiver dimensions, and official hardware, including the signature Maxim Steel HATEBRAKE muzzle device and free-float M-LOK handguard with pre-installed M-RAX handstop.


• Glock Magazine Cross-Compatibility: No need to buy an entirely new magazine ecosystem. The MD9-K native lower receiver takes standard VFC/Umarex Glock 17, 18C, 19, and 45 gas magazines (including extended 50-round stick mags), allowing you to share sidearm mags straight into your primary.


• Lightweight CNC Aluminium Bolt: Equipped with a precision CNC aluminium bolt carrier set. The reduced weight increases cycle speed and gas efficiency, giving you lightning-fast split times and snappy full-auto response on Green Gas.


• Maxim Gen7 SCW Retractable Stock: Adjust your overall length from a tiny 435mm (collapsed) for room clearing or vehicle storage to 555mm (extended) when you need a stable shoulder position for range.


• Full Ambidextrous Controls: Fitted with an ambidextrous charging handle, steel mag catch, and fire selector, making transitions between left and right shoulders seamless during aggressive cornering.


• Textured Magwell Hold: The flared, deeply textured lower receiver provides a secondary hand grip point for shooters who prefer a tight "magwell hold" posture in ultra-confined spaces.

Pro Tip: Because the MD9-K runs on VFC's Glock engine geometry, using high-capacity 50-round extended Glock magazines gives you maximum suppressive fire during indoor skirmishes. Keep the bolt carrier rails lightly lubricated with pure silicone oil to preserve high-speed cycle times!
