CM.052S, GEN-2 [CYMA]

The CM.052S GEN-2 machine gun replica by CYMA is an electric RPKS-74 replica with a side-folding stock, wooden external parts and an reinforced V3 gearbox configuration. The GEN-2 series, V3 GEN-2 gearbox with quick spring change system and CYMA V3 MOSFET system support stable replica performance in a fire support role.

Construction and design

The CM.052S GEN-2 is based on the RPKS-74 machine gun design, an extended AK platform adapted for intensive support fire. Its distinctive long silhouette, steel bipod and extended barrel support the use of the replica at medium and longer distances.

The replica is made from a combination of wood, polymer and metal, with selected steel elements. The wooden handguard and stock give the construction the classic appearance of the RPKS-74, while the polymer pistol grip supports secure handling during shooting.

Steel elements include the bipod, flash hider, receiver cover, receiver, trigger guard, magazine catch and cleaning rod. This build increases the rigidity of key external parts and reinforces the utilitarian character of the replica.

Ergonomics and handling

The side-folding stock allows the overall length of the replica to be reduced during transport and makes it easier to carry outside the game. The battery compartment is located in the stock, keeping the power supply hidden without interfering with the front end of the replica.

The bipod enables more stable fire from a supported position. In a support replica, this makes it easier to control longer bursts and maintain a repeatable shooting stance.

The serial number is located on the left side of the receiver.

Internal parts and mechanics

The model uses a V3 GEN-2 gearbox with a quick spring change system (QSC). This solution enables more efficient adjustment of the replica's power to field limits without fully disassembling the gearbox.

Inside, the replica uses 8 mm steel ball bearings, steel gears with an 18:1 ratio and a piston with a full steel rack and aluminium piston head. This configuration supports smooth mechanism operation and improved resistance of internal components to loads generated during use.

The replica features a steel type 0 cylinder, aluminium cylinder head and a 19.7 mm Teflon nozzle. The steel bearing spring guide supports proper spring alignment during the gearbox cycle.

The drive system is powered by a neodymium Hi-Torque motor, which supports trigger response and the operation of the mechanism in a support replica configuration.

Electronic system

The CM.052S GEN-2 is equipped with a CYMA V3 MOSFET system. The system supports the operation of the electrical setup, improves current flow control and affects the replica's working culture during burst fire.

The replica uses a T-connect plug, which provides a more stable electrical connection than older connector types used in AEG replicas.

Hop-up and inner barrel

The model features a metal hop-up chamber, which enables adjustment of the BB trajectory depending on BB weight and engagement distance.

The inner barrel has a diameter of 6.03 mm and a length of 640 mm.

Performance and precision

The factory FPS is ~390-400 FPS. This power level allows the replica to be used in outdoor games, especially in fire support tasks.

The 20 RPS rate of fire supports continuous fire and effective control of a selected sector. Combined with Hi-Cap 800 BB magazines, the replica allows longer fire without frequent reloading.

Power supply

The battery compartment is located in the side-folding stock. The replica is equipped with a T-connect plug.

Manufacturer

CYMA is one of the most recognizable AEG replica manufacturers, especially associated with designs based on AR15 and AK platforms. The GEN-2 series develops the brand's proven constructions with a more modern gearbox configuration, MOSFET system and internal components prepared for intensive work in airsoft conditions.
Each replica undergoes a pre-delivery inspection. It is checked and test-fired on an XCORTECH X3200 chronograph.
