CQB Agility and Polymer Strength

True to the real firearm, the UMP45 GBB utilizes a high-strength Fibre Reinforced Polymer body. This material choice results in a lightweight profile (around 2.5kg) that significantly enhances agility in Close-Quarters Battle (CQB) environments, allowing for faster cornering and aiming transitions. The side-folding stock further compacts the UMP's profile, making it highly versatile for transport or use in vehicles and confined spaces.

Authentic Controls and Firepower

This replica is built to mirror the real-steel experience. It features full Ambidextrous Controls on the fire selector and magazine release, making it intuitive for all users.

The select-fire capability includes Safe, Semi-Auto, Full-Auto, and the highly functional 2-Round Burst mode—a signature UMP feature that allows for ammo conservation while ensuring a fast double-tap on target.

The Green Gas blowback action is strong and crisp, delivering a realistic mechanical sound and tactile feedback with each shot.

Optimized for the Tactical Player

The UMP45 features VFC’s detailed internal design, including a lightweight aluminium alloy bolt assembly and steel reinforcement in critical areas like the bolt catch.

For superior accuracy, the Adjustable Hop-Up system is designed for quick external adjustment via the muzzle, making it easy to dial in your range on the fly.

With a 20mm Picatinny rail section on all four sides of the handguard, accessory mounting—from foregrips to tactical lights—is effortless.
