Licensed H&K MP5 CM.041J Replica with Eshooter ETU, GEN-2 [Umarex]

The licensed MP5 A3 airsoft submachine gun from the CYMA Platinum series is an electric AEG based on the configuration of the MP5 A3 firearm counterpart, with a classic handguard and a three-position retractable stock. The GEN-2 V2 gearbox, Kestrel V2 MOSFET/ETU and QSC quick spring change system support a fast operating cycle, electronic control of the mechanism and easier adjustment of the replica to game limits. The compact MP5 A3 design facilitates handling during dynamic CQB games and operations in confined spaces.

MP5 A3 construction and CQB use

The replica is made of nylon and aluminum. Its weight without the magazine is ~2836 g. The airsoft submachine gun measures 575 mm with the stock collapsed and 725 mm with the stock extended.

The construction is based on the configuration of the MP5 A3 firearm counterpart. The classic handguard and retractable stock retain the characteristic layout of this version. The stock offers three adjustment positions, allowing the replica's length to be adapted to the user's preferred stance and handling style.

With the stock collapsed, the replica retains compact dimensions that facilitate maneuvering inside buildings, moving through narrow passages and quickly transitioning between targets. Extending the stock provides a more stable shoulder position when firing.

The replica has four sling attachment points. The first is located near the front pin, the second on the magazine well, and the third and fourth around the stock. Their placement allows the carrying configuration to be adapted to the user's preferences and sling setup.

Licensed markings are located near the magazine well, on the upper part of the receiver and on the left side of the trigger housing. An individual serial number is located on the magazine well.

Muzzle device

The replica features a muzzle device with a Tri-Lug mounting system and a 14 mm CCW thread. The two mounting standards allow the use of appropriately matched tracer units and dummy sound suppressors.

The construction supports the installation of the MP5K, MP5 PDW QD Spitfire tracer unit, which uses a quick-detach mounting system designed for the MP5 platform. A tracer unit can make it easier to observe the BB trajectory during CQB games in poorly lit indoor areas.

Sights and optics mounting

The replica is equipped with standard iron sights consisting of a diopter rear sight and a hooded front sight.

Between the sights is a mounting point for the Rail mount for MP5/G3 - low [CYMA] RIS rail. The rail allows the use of compatible red dot sights, which facilitate faster target acquisition during dynamic games and short-range engagements.

Controls and hop-up adjustment

The replica uses the classic ambidextrous control layout of the MP5 platform. The magazine release lever is located in front of the trigger guard, facilitating operation during magazine changes.

Access to the polymer MP5 hop-up chamber is gained by pulling the cocking handle back and locking it in the dedicated notch. Exposing the chamber simplifies hop-up adjustment without requiring the replica to be disassembled.

Internal parts and mechanics

The MP5-version GEN-2 V2 gearbox is equipped with the QSC quick spring change system located inside the gearbox.

The mechanism uses CNC-machined 13:1 short-stroke gears, 8 mm steel ball bearings and a piston with full steel teeth. Power is provided by a long-type high-torque neodymium motor.

The pneumatic system includes a set of silent aluminum heads, a steel type 2 cylinder and a 21.00 mm Teflon nozzle sealed with an O-ring. The steel spring guide is equipped with a bearing.

Electronic system and power supply

The replica uses the Kestrel V2 MOSFET/ETU, which electronically controls the mechanism and supports a fast trigger response.

The wiring is terminated with a T-connect plug. The battery compartment is located in the front section of the replica, beneath the handguard.

The replica reaches a rate of fire of ~26 RPS when used with an appropriate battery. The brass AEG inner barrel is 225 mm long and has a diameter of 6.03 mm.
