CM.070, GEN-2 [CYMA]

The CM.070 GEN-2 airsoft rifle by CYMA is an electric AEG based on the AR15 platform, designed for dynamic CQB games and short- to medium-range engagements. The replica combines a GEN-2 V2 gearbox with a Quick Spring Change (QSC) system accessible through the stock tube, a CYMA ETU system, and an ambidextrous magazine release, making the rifle easier to operate for both right- and left-handed users.

Construction and design

The CM.070 GEN-2 replica is constructed from a combination of metal and polymer components. The metal receiver forms the basis of the construction, while the pistol grip and SF-type stock are made of polymer.

The rifle measures 785 mm with the stock fully collapsed and 865 mm with the stock fully extended. Its compact dimensions make it easier to handle in confined spaces and during dynamic CQB games.

The construction also features metal controls and folding iron sights. These can serve as the primary aiming system or be folded down when using additional optics.

Ergonomics and handling

The CM.070 GEN-2 features an ambidextrous magazine release, allowing convenient operation for both right- and left-handed users.

The enlarged trigger guard provides additional space around the trigger, making the replica easier to handle while wearing tactical gloves.

The SF-type stock features six adjustable positions, allowing the user to adjust its length according to their body size, tactical equipment, and preferred shooting position.

The rear end plate features ambidextrous sling attachment points, allowing the carrying configuration to be adapted to the user's preferences.

The functional bolt catch allows the mock bolt carrier to be locked in the rear position, providing access to the hop-up chamber for BB backspin adjustment.

Internal components and mechanics

The replica features a GEN-2 V2 gearbox equipped with 8 mm ball bearings and gears with an 18:1 ratio.

The internal configuration includes a piston with a full steel tooth rack and an aluminum piston head. The pneumatic system features a Type 0 cylinder, an aluminum cylinder head, and a 21 mm Teflon nozzle.

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

The mechanism is driven by a long-type high-torque motor, supporting gearbox operation and trigger response.

The gearbox also features a Quick Spring Change (QSC) system, allowing the main spring to be replaced through the stock tube.
In the CM.070 GEN-2, the spring can be replaced through the stock tube without removing the gearbox from the replica's receiver or opening the gearbox shell. This system makes it easier to adjust the replica's power configuration to meet the requirements of different airsoft games while reducing the number of steps required for spring replacement.

Electronic system

The CM.070 GEN-2 features a CYMA ETU system, responsible for electronically controlling the trigger mechanism.

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

Performance and accuracy

The replica has a rate of fire of ~18 RPS, allowing sustained automatic fire during dynamic airsoft games.

The model features a brass inner barrel measuring 345 mm in length and 6.03 mm in diameter, supporting shot-to-shot consistency.

The metal rotary 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.

Power supply

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

The battery compartment is located inside the stock tube of the SF-type stock.
