Umarex H&K UMP Competition Series Airsoft AEG SMG (Black)

Deploy a legendary submachine gun platform optimized for close-quarters dominance and hard-hitting tactical backup. The Umarex H&K UMP Competition Series AEG is an officially licensed, ultra-compact 6mm airsoft rifle bearing authentic Heckler & Koch GmbH trademarks. Engineered with a rugged, lightweight reinforced ABS body and a powerhouse full metal gearbox, this submachine gun delivers structural dependability whether you are running point in tight CQB grids or packing a rapid-fire secondary for sniper support.

Overview

The Umarex H&K UMP bridges the gap between carbine-class range and submachine gun maneuverability. It features a side-folding skeleton stock that instantly trims its profile for high-speed building entries and compact vehicle operations. A full-length top Weaver/Picatinny receiver rail provides massive real estate for your preferred optics—such as the Valken RDA20 Red Dot Sight—while the integrated tri-rail RIS handguard offers dedicated mounting space for flashlights, lasers, and vertical foregrips.

Beneath its impact-resistant polymer exterior, this replica is built for competitive skirmishes. It features a Version 3 full metal reinforced gearbox with steel gears, providing an incredibly reliable and fully upgradeable foundation capable of managing future performance updates. Out of the box, it punches out a very balanced 315 FPS (0.92 Joules), making it safe and compliant for strict indoor CQB velocity limits. Combined with an adjustable hop-up unit, integrated front and adjustable rear sights, and a massive 400-round high-capacity magazine, the UMP ensures you have the sustained firepower needed to lock down objectives.

Ideal For

• High-Speed CQB and Indoor Muzzle-Restricted Fields
• Recon Operators and Scout Roles Demanding Lightweight Firepower
• Snipers Requiring a Compact, High-Capacity Automatic Backup Weapon System
• Value-Focused Players Seeking a Full Metal Gearbox Starter Package

Field Tips

• Access the battery compartment by popping open the upper receiver assembly. We recommend using a high-quality 7.4v stick LiPo or a 9.6v stick NiMH to maximize your rate of fire while fitting cleanly into the receiver channel.
• Make sure to wind the winding wheel on the bottom of the 400-round high-capacity magazine completely before your match to ensure uninterrupted feeding during full-auto suppression.
• Pair this platform with a low-profile red dot sight on the top weaver rail to easily acquire your sight picture over the integrated front post hood.
• Keep the Version 3 gearbox running smoothly by applying a drop of high-grade airsoft silicone oil to your hop-up bucking every few months to maintain consistent compression.
