Lightweight Frame, Heavy Recoil

Built with high-strength Fibre Reinforced Polymer for the receiver and stock—mimicking the real H&K design—the UMP9 GBB is remarkably lightweight (around 2.3kg). This lightness is critical for CQB and high-mobility skirmishing. However, the internal Gas Blowback system delivers a powerful, satisfying recoil impulse that belies its light frame, providing realistic auditory and tactile feedback with every shot.

Authentic Operation and Firepower

This model includes the complete suite of authentic features: full Ambidextrous Controls and four distinct selector positions: Safe, Semi-Auto, Full-Auto, and the highly sought-after 2-Round Burst mode. This functional burst capability allows experienced players to conserve gas and ammunition while guaranteeing a fast double-tap on target. The distinctive curved 30-round 9mm magazine aesthetic provides visual realism and excellent gas efficiency.

Designed for Performance and Modularity

The VFC UMP9 features a robust internal design, including a lightweight aluminum alloy bolt assembly and a quick-adjust Hop-Up system accessible directly at the muzzle with an Allen key. This allows for easy field tuning to optimize accuracy with different BB weights. Furthermore, the standard Picatinny rail mounting points (top and handguard) allow for easy customization with your preferred optics, grips, and lights, making this an ideal choice for a versatile tactical SMG.
