Dominate close-quarters engagements and run an absolute tactical icon with the Umarex HK MP5 SD6 Competition Series AEG. Fully licensed by Heckler & Koch, this high-performance airsoft SMG delivers the legendary, stealth-focused look of the suppressed MP5 favored by elite counter-terrorism forces worldwide. Built for maximum speed, mobility, and reliability on the field, it functions as the ultimate close-quarters weapon system.

Overview

The Umarex HK MP5 SD6 features a lightweight, high-durability injection-molded polymer receiver paired with a rugged metal alloy outer barrel, striking the perfect balance between field agility and robust build quality. The iconic mock suppressor completes its profile, giving you an aggressive tactical edge. Ambidextrous HK-style selector switches ensure seamless, comfortable operation for both left- and right-handed operators.

Adaptability and performance are standard with this platform. An adjustable collapsible stock allows you to instantly transition between a compact 660mm profile for tight corners and an extended 800mm length for stable shoulder support. The charging handle functions realistically and locks open, giving you immediate access to the adjustable hop-up unit. Internally, a fully upgradeable Version 2 full metal gearbox pairs with a long-type motor to deliver a consistent velocity range of 330 to 350 FPS out of the box. Ready for intense skirmishes, this package comes complete with two 200-round high-capacity magazines.

Ideal For

• Pointmen, Assaulters, and High-Speed CQB Players
• Elite Counter-Terrorism and Special Forces MilSim Operators
• Hobbyists Seeking a Light, Agile, and Dependable Primary Platform

Field Tips

• The handguard houses the battery compartment. Use a slim profile 7.4v LiPo stick or split configuration to easily seat the handguard without pinching the wiring.
• Lock the charging handle into the top rear notch to comfortably adjust your slider hop-up, then slap the handle down to send it forward.
• To ensure smooth feeding during full-auto fire, keep the bottom winding wheels of the high-capacity magazines fully tensioned before rolling out.
• Clean the ~210mm inner barrel with a non-abrasive cleaning rod and microfiber patch regularly to maintain tight groupings inside close quarters.
