CM.052S, GEN-2 [CYMA]

The CM.052S GEN-2 airsoft light machine gun replica by CYMA is an electric AEG based on the RPKS-74 design, featuring a side-folding stock, wooden furniture, and a steel bipod. The replica combines a GEN-2 V3 gearbox with a Quick Spring Change (QSC) system, a CYMA V3 MOSFET, and steel structural components, supporting its use in a fire support role during airsoft games.

Construction and design

The CM.052S GEN-2 replica reproduces the distinctive silhouette of the RPKS-74 light machine gun, characterized by its extended barrel, side-folding stock, and bipod for firing from supported positions.

The construction combines steel, metal, wood, and polymer. Steel components include the receiver, receiver cover, flash hider, trigger guard, magazine catch, cleaning rod, and bipod.

The wooden handguard and stock emphasize the classic appearance of the RPKS-74, while the polymer pistol grip completes the construction.

The replica features an individual serial number located on the left side of the receiver.

Ergonomics and handling

The side-folding stock allows the overall length of the replica to be reduced during transportation and handling in confined spaces.

The steel bipod provides stable support for the front of the replica when firing from a prone position or using a suitable surface. This helps maintain a consistent shooting position during longer bursts of fire.

The RPKS-74 design is suited to the role of a support weapon during outdoor airsoft games.

Internal components and mechanics

The replica features a GEN-2 V3 gearbox equipped with 8 mm steel ball bearings and 18:1 steel gears.

The internal configuration includes a piston with a full steel tooth rack and an aluminum piston head. The pneumatic system features a Type 0 steel cylinder, an aluminum cylinder head, and a 19.7 mm Teflon nozzle.

The bearing-mounted steel spring guide supports proper spring operation during the firing cycle.

The mechanism is driven by a high-torque motor with neodymium magnets, supporting efficient mechanical operation and trigger response.

The gearbox also features a Quick Spring Change (QSC) system, allowing the main spring to be replaced without opening the gearbox shell.
To access the QSC system, the gearbox must first be removed from the replica's receiver. Once removed, the spring can be replaced without opening the gearbox shell, making it easier to adjust the replica's power configuration to meet the requirements of different airsoft games.

Electronic system

The CM.052S GEN-2 features a CYMA V3 MOSFET, responsible for controlling the operation of the replica's electrical system.

The MOSFET supports electrical system operation and trigger response during semi-automatic and fully automatic fire.

Performance and accuracy

The replica has a factory muzzle velocity of ~390-400 FPS and a rate of fire of ~20 RPS.

The model features a 640 mm inner barrel with a diameter of 6.03 mm, supporting shot-to-shot consistency.

The metal hop-up chamber allows adjustment of BB backspin, enabling the user to adapt the BB trajectory to the weight of the BBs used and shooting conditions.

The rate of fire of ~20 RPS, combined with hi-cap magazines holding 800 BBs each, allows longer bursts of fire without frequent magazine changes, making the replica particularly useful in a fire support role.

Power supply

The replica uses a T-connect connector. The battery is housed inside the side-folding stock.

Recommended accessories include 7.4V and 11.1V LiPo batteries.
