Umarex HK G36 K 6mm AEG with EFCS, EBB recoil, metal KeyMod handguard, quick spring release, and authentic full-metal design.
The Umarex H&K G36K (model 2.6441X) is a compact, HK‑licensed AEG built for close‑quarters performance and realism. It pairs an EFCS electronic gearbox with an Electric Blow Back system for authentic recoil feel while keeping reliable, consistent shots for skirmish play. The full‑metal KeyMod handguard, IDZ buttstock and ambidextrous controls make this a versatile platform for right‑ or left‑handed players.
Designed with durability in mind, the G36K sports full‑metal gears, an adjustable hop‑up, and a quick spring release for easy chrono/spring swaps. The 350 mm barrel and recommended 0.20 g BBs balance accuracy and controllability at game‑legal energy levels (<1.0 J). Its 45‑round mid‑cap magazine keeps your profile low while still offering fast follow‑ups when the action heats up.
Ergonomics are classic G36 — compact overall length (800 mm) with a lightweight, tactical silhouette that’s easy to shoulder and manoeuvre in tight spaces. The rifle runs on LiPo batteries (battery not included) and is set up for players who want a ready‑to‑play licensed replica with modern internals and upgrade potential.
Whether you’re fielding a squad or want a realistic, reliable EBB AEG for milsim and CQB, the Umarex G36K delivers authentic HK aesthetics with solid internal components and practical features for regular play.

Good quality
My new favourite case, neatly packed and speedily shipped. I am over the moon.
I had my doubts, because the picture isnt that clear. However when it arrived I was pleasantly surprised. Not only is this warm, the material and quality is outstanding.
This is by far the BEST Camo suit we have ever bought. We will absolutely be referring Gunmansa to all our friends that need tactile gear.
5 STARS ALL THE WAY!!!!

Haven't had a chance to shoot it but damn it looks so beautiful and realistic this is a 10/10 product!
A great product and does what it is supposed to do
Perfect replacement for previous unit. Plug and play option. No hassles.
Very satisfied with this purchase. Pellets are consistent, clean, and group well at range. Hollow point hits hard and the 500 count tin gives good value for money. Gunmansa shipped fast and the tin arrived sealed with no damage. Would buy again. 5/5
