CM.052 RPK-74, GEN-2 [CYMA]

The RPK-74 electric airsoft machine gun replica by CYMA is an AEG model reproducing the distinctive design of the RPK-74 light machine gun, intended for airsoft games. The replica combines a CYMA V3 (ZEUS) MOSFET/ETU system, a wooden stock and handguards, and a steel bipod, allowing stable support while firing.

Construction and design

The CYMA RPK-74 replica is constructed from a combination of steel, aluminum, nylon, and wood. The wooden stock and handguards emphasize the distinctive appearance of the RPK-74 light machine gun, while the nylon pistol grip complements its classic design.

The outer barrel is made of aluminum. The steel bipod supports the front of the replica when firing from a prone position or using a suitable surface, helping the user maintain a stable shooting position.

The fit of the components supports structural rigidity during use. The replica measures 1075 mm in length and weighs ~4150 g without the magazine. An individual serial number is located on the receiver.

Optics and accessory mounting

The receiver features a side-mounted dovetail rail, based on the system used in the original firearm. It allows the use of a suitable mounting rail for installing an additional optic.

The outer barrel features a 14 mm CCW thread, allowing the installation of compatible muzzle devices, including mock suppressors and tracer units.

Ergonomics and handling

The replica features two attachment points for a tactical sling, positioned similarly to those on the original RPK-74.

One attachment point is located on the stock, while the other is positioned on the handguard mounting component. This arrangement allows the replica to be carried using a suitable sling.

Internal components and mechanics

The replica features a V3 gearbox equipped with 18:1 gears, 8 mm ball bearings, and a piston with a full steel tooth rack.

The bearing-mounted steel spring guide supports proper spring operation during the firing cycle. The mechanism is driven by a short-type high-torque motor with neodymium magnets, supporting responsive trigger operation.

The pneumatic system includes a Type 0 cylinder, a silent piston and cylinder head set, and a 19.70 mm Teflon nozzle equipped with an O-ring seal.

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 RPK-74 features a CYMA V3 (ZEUS) MOSFET/ETU system, responsible for electronically controlling the operation of the mechanism.

The system supports trigger response and electrical system operation during firing.

Performance and hop-up system

The replica has a factory muzzle velocity of ~380 FPS in the Stock configuration and a rate of fire of ~20 RPS.

When purchasing the muzzle velocity adjustment service, the Medium (~350 FPS) and Low (~300 FPS) configurations are also available, allowing the replica's power to be adapted to different airsoft game requirements.

The model features a brass AEG inner barrel measuring 640 mm in length and 6.03 mm in diameter.

The metal AK-type hop-up chamber allows adjustment of BB backspin, enabling the user to adapt the BB trajectory to shooting conditions.

Power supply

The replica uses a T-connect connector and is compatible with dedicated 7.4 V and 11.1 V LiPo batteries.

The battery is housed inside the wooden stock.
