The Umarex H\u0026amp;K UMP Competition Series AEG is an officially licensed, ultra-compact 6mm airsoft rifle bearing authentic Heckler \u0026amp; 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gda-section\"\u003e\n\u003ch2 class=\"gda-sub\"\u003eOverview\u003c\/h2\u003e\n\u003cp\u003eThe Umarex H\u0026amp;K UMP bridges the gap between carbine-class range and submachine gun maneuverability.

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.\u003c\/p\u003e\n\u003cp\u003eBeneath 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gda-section gda-grid\"\u003e\n\u003cdiv\u003e\n\u003ch2 class=\"gda-sub\"\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eOfficially Licensed Replica with Authentic H\u0026amp;K Trademarks\u003c\/li\u003e\n\u003cli\u003eImpact-Resistant, Reinforced ABS Polymer Body\u003c\/li\u003e\n\u003cli\u003eSide-Folding Skeleton Tactical Stock for Tight CQB Profiles\u003c\/li\u003e\n\u003cli\u003eFull-Length Top Rail for Red Dots and Primary Optics\u003c\/li\u003e\n\u003cli\u003eIntegrated Quad-Sided RIS Rails for Tactical Accessories\u003c\/li\u003e\n\u003cli\u003eVersion 3 Full Metal Reinforced Gearbox (Fully Upgradeable)\u003c\/li\u003e\n\u003cli\u003eHigh-Capacity 400-Round Magazine Included\u003c\/li\u003e\n\u003cli\u003eIntegrated Front and Fully Adjustable Rear Sights\u003c\/li\u003e\n\u003cli\u003eDual Front and Rear Heavy-Duty Sling Mount Anchors\u003c\/li\u003e\n\u003cli\u003eCompact Footprint — Ideal Primary or Automated Sniper Backup\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch2 class=\"gda-sub\"\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Umarex (Licensed by H\u0026amp;K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e H\u0026amp;K UMP Competition Series\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Source:\u003c\/strong\u003e Electric (AEG)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaliber:\u003c\/strong\u003e 6mm Airsoft BB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMuzzle Velocity:\u003c\/strong\u003e 315 FPS \/ 0.92 Joules (with 0.20g BBs)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMagazine Capacity:\u003c\/strong\u003e 400-Round High-Capacity Magazine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Barrel Length:\u003c\/strong\u003e 205mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGearbox:\u003c\/strong\u003e Version 3 Full Metal Reinforced (Upgradeable)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Type:\u003c\/strong\u003e Short Type\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFire Modes:\u003c\/strong\u003e Semi \/ Fully Automatic, Safety\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery Wiring:\u003c\/strong\u003e Front-Wired (Standard Small Tamiya Connector)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHop-Up:\u003c\/strong\u003e Yes, Fully Adjustable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Matte Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShipping Restriction:\u003c\/strong\u003e Ships Only Within United States\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gda-section gda-highlight\"\u003e\n\u003ch2 class=\"gda-sub\"\u003eWhy Choose The Umarex H\u0026amp;K UMP?\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Heckler \u0026amp; Koch engravings provide premium realism for MilSim players and collectors\u003c\/li\u003e\n\u003cli\u003eReinforced ABS build keeps the platform lightweight and agile without sacrificing structural strength\u003c\/li\u003e\n\u003cli\u003eThe robust Version 3 gearbox uses standard internal geometry, making upgrade components widely available\u003c\/li\u003e\n\u003cli\u003eMassive 400-round out-of-the-box magazine capacity outperforms standard SMG mid-caps\u003c\/li\u003e\n\u003cli\u003eSide-folding stock makes it highly transportable and easy to store on a sniper scabbard or pack harness\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gda-section\"\u003e\n\u003ch2 class=\"gda-sub\"\u003eIdeal For\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eHigh-Speed CQB and Indoor Muzzle-Restricted Fields\u003c\/li\u003e\n\u003cli\u003eRecon Operators and Scout Roles Demanding Lightweight Firepower\u003c\/li\u003e\n\u003cli\u003eSnipers Requiring a Compact, High-Capacity Automatic Backup Weapon System\u003c\/li\u003e\n\u003cli\u003eValue-Focused Players Seeking a Full Metal Gearbox Starter Package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gda-section\"\u003e\n\u003ch2 class=\"gda-sub\"\u003eField Tips\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAccess the battery compartment by popping open the upper receiver assembly.
