Umarex H&K G36C Competition Series AEG Airsoft Rifle
Umarex H&K G36C Competition Series Airsoft Electric Gun (AEG)
Dominate CQB fields and mid-range skirmishes without breaking your budget. The Umarex H&K G36C Competition Series packs high-end performance specs into an affordable, tournament-ready package. Officially licensed with authentic Heckler & Koch GmbH trademarks, this 6mm electric rifle delivers top-tier ergonomics and uncompromising reliability straight out of the box.
Overview
Built around a highly upgradeable, reinforced full metal Version 3 gearbox, the G36C is entirely Tokyo Marui system compatible, opening the door for endless internal modification, custom tuning, and aftermarket parts. The lightweight yet rugged exterior features a side-folding skeleton stock that shrinks your tactical profile in tight corridors, while integrated front and adjustable rear iron sights guarantee fast target acquisition right out of the box.
Customization options run deep on this compact platform. A full-length top Picatinny rail accommodates standard optics and scopes, while dedicated front handguard rails allow for clean mounting of tactical flashlights, lasers, and custom configurations. The front-wired compartment hooks up via a standard small Tamiya connector, pushing energy through a high-torque short type motor for crisp trigger response in semi-automatic or fully automatic firing modes.

Field Tips
- We recommend pairing this rifle with our Valken RDA20 Red Dot Sight on the top rail for lightning-fast target tracking.
- When routing your battery inside the front handguard, ensure wires run parallel along the side of the barrel to avoid pinching when sliding the handguard back into place.
- To load and feed the included 400-round high-capacity magazine, open the top trapdoor, fill it completely with BBs, and spin the bottom wheel until the clicking resistance changes.
- Before long-term storage, fold the skeleton stock to save space, and always turn the adjustable hop-up completely dial-off to preserve bucking elasticity.

Frequently Asked Questions
Does this package include a battery and charger?
Yes. The factory package includes a starter 8.4v 1600mAh split-type NiMh battery and standard wall charger. However, for faster trigger response and optimal field performance, we recommend upgrading to a high-quality 9.6v NiMh stick or 7.4v LiPo stick battery.
Can I upgrade the internal components of this rifle?
Absolutely. The rifle features a full metal Version 3 gearbox that is entirely compatible with Tokyo Marui system parts. This makes it incredibly easy to install aftermarket gears, pistons, motors, hop-up buckings, or electronic trigger units (ETUs).
What weight BBs are recommended for the G36C?
For the best balance of velocity and accuracy at 315 FPS, we recommend high-quality, seamless 6mm BBs weighing 0.20g or 0.25g. Avoid low-grade or recycled BBs, as they can crack internally and damage your inner barrel or hop-up unit.
How does the stock function for close-quarters play?
The G36C features a folding skeleton stock. Pressing the release button near the hinge allows the stock to lock securely against the right side of the receiver, shortening your rifle's profile significantly for tight CQB environments.
Can I mount aftermarket tactical grips or optics onto this model?
Yes. The rifle comes equipped with a full-length top 20mm Picatinny rail for red dots or scopes, along with dedicated bottom and side rails on the handguard for mounting vertical foregrips, flashlights, and lasers.
