H&K MP5A4 RIS Full Metal AEG with Eshooter ETU GEN-2 (Umarex/Cyma - Black - CM041B)

For players who demand classic special operations aesthetics paired with cutting-edge electronic trigger control, the H&K MP5A4 RIS Full Metal AEG (CM041B) is the definitive CQB platform. Produced by Cyma under official licence from Umarex and Heckler & Koch, this model features authentic stamped trademarks, a rock-solid all-metal receiver, and an upgraded Eshooter ETU Gen-2 gearbox build.

Pre-Installed Eshooter ETU Gen-2 Electronics Setting this replica apart from standard legacy MP5 AEGs is the factory-fitted Eshooter ETU Gen-2 (Electronic Trigger Unit). Replacing traditional mechanical trigger contacts, the optical ETU provides immediate, micro-switch trigger response and protects internal circuitry from electrical arcing. Players can easily program custom fire modes—including crisp 3-round burst settings—and take advantage of smart features such as active braking, pre-cocking, and low-voltage battery protection, ensuring rapid cycle completion on every semi-auto trigger pull.

Heavy-Duty Full Metal Construction & Tactical RIS The CM041B is crafted with a dense metal alloy upper receiver, metal cocking tube, and durable polymer lower receiver/pistol grip, replicating the genuine weight, balance, and feel of the iconic 9mm submachine gun. The front end is outfitted with an aluminium tri-rail 20mm Picatinny RIS handguard, providing immediate mounting real estate for tactical flashlights, laser aiming modules, and vertical foregrips. At the rear, the solid fixed A4-style stock offers rock-solid shoulder stability and houses generous space for large-capacity LiPo batteries.
