CM.513 Sport Line, GEN-2 [CYMA]

The CM.513 GEN-2 by CYMA is a lightweight AR15-based replica designed for versatile use in both CQB environments and medium-range engagements. The Sport Line construction provides low weight, a QSC quick spring change system, and the CYMA V2 MOSFET unit, which supports smoother and more responsive operation.

Sport Line Series

The Sport Line series by CYMA was developed for users looking for a lightweight and comfortable replica suitable for regular gameplay. The use of polymer external components helped reduce overall weight while maintaining solid fitment between elements.

The lower weight improves mobility during dynamic CQB gameplay and increases comfort during longer sessions. The AR15 platform offers intuitive handling and wide compatibility with aftermarket accessories.

Construction

The receiver is made from polymer, helping achieve a well-balanced and comfortable setup. The replica features a 14 mm CCW thread for mounting airsoft-standard muzzle devices.

The model includes an individual serial number located on the lower receiver. Stable fitment and the absence of noticeable wobble support more confident handling during intensive use.

Ergonomics and Handling

The CM.513 GEN-2 uses the classic AR15 layout with ergonomic controls and convenient access to the hop-up adjustment system. The battery is housed inside the stock, allowing easier replacement while helping maintain proper balance.

The replica uses a T-connect plug and is compatible with 7.4V and 11.1V LiPo batteries. The integrated CYMA V2 MOSFET supports faster trigger response and improves the overall operation of the electrical system.

Internal Parts and Mechanics

The GEN-2 version features a V2 gearbox equipped with the QSC quick spring change system, allowing easier adjustment of the replica's performance for different gameplay environments.

The system is based on steel gears, 8 mm bushings, and a type 2 cylinder. The replica uses a polymer air nozzle sealed with an O-ring, along with a standard pneumatic system featuring a flat piston head and cylinder head.

The piston is equipped with a single steel tooth, while the metal spring guide includes a stabilizing washer.

Performance and Accuracy

The replica features a polymer rotary hop-up chamber that allows convenient and precise BB spin adjustment.

The 385 mm long 6.04 mm AEG inner barrel supports shot consistency and stable BB trajectory at medium range. Factory muzzle velocity is approximately 390 FPS in stock configuration.

The model reaches a rate of fire of approximately 19 RPS when used with a suitable LiPo battery.
