Umarex Heckler & Koch G36K — EFCS KeyMod EBB AEG (2.6441X)
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.
