CM.508 Sport Line, GEN-2 [CYMA]

The CM.508 GEN-2 by CYMA is a lightweight AR15-based replica designed for players looking for a mobile setup for CQB and mid-range gameplay. The GEN-2 version features a V2 gearbox with a quick spring change system, a rotary hop-up chamber, and the CYMA V2 MOSFET, offering good balance, responsive electrical system performance, and precise hop-up adjustment.

Sport Line Series

The Sport Line series is a CYMA product line developed to reduce replica weight while retaining the proven internal design characteristic of the manufacturer's platforms.

Thanks to the use of durable polymer components, the replica remains comfortable to operate. For the user, this means easier handling during dynamic gameplay, more comfortable target acquisition, and reduced fatigue during extended sessions.

External Construction

The receiver, handguard, and most external components are made of polymer, allowing for improved balance and reduced overall weight. The construction retains the classic AR15 layout and intuitive control placement.

The model is equipped with a 14 mm CCW thread for mounting compatible muzzle devices. The replica also features an individual serial number located on the lower receiver.

Well-fitted components and the absence of noticeable wobble support structural stability and user comfort.

Ergonomics and Handling

The lightweight construction and front handguard battery placement support comfortable handling and fast maneuverability in tight spaces. The AR15 platform remains intuitive for both new users and experienced players.

Thanks to the rotary chamber design, hop-up adjustment is more convenient and more precise than in traditional solutions. This allows easier BB trajectory tuning depending on the ammunition weight used.

Internal Parts and Mechanics

Inside, the replica uses a V2 gearbox. The construction features 8 mm bushings, steel gears, a type 2 cylinder, and a sealed 20.96 mm nozzle.

The pneumatic system is based on standard components with a flat cylinder head and a piston equipped with a steel tooth. The installed long-type standard motor provides stable operation and fast drivetrain response.

The GEN-2 version is equipped with a QSC quick spring change system, allowing more convenient power adjustment for different gameplay types without fully disassembling the gearbox.

Electronic System - CYMA V2 MOSFET

The model uses the CYMA V2 MOSFET system, which improves electrical system performance and enhances trigger response. This solution reduces contact wear and supports more stable operation with LiPo batteries.

The replica delivers approximately 390 FPS in the factory configuration and reaches a rate of fire of around 19 RPS.

Performance and Accuracy

The CM.508 GEN-2 is equipped with a 6.04 mm brass inner barrel with a length of 385 mm. This configuration supports accuracy and shot consistency during mid-range gameplay.

The adjustable hop-up system allows more precise BB trajectory control, which may improve effectiveness during dynamic engagements.

Power Supply

The replica uses a T-connect plug and is compatible with both 11.1V and 7.4V LiPo batteries. The battery is housed inside the front handguard, helping maintain good ergonomics and convenient access during battery replacement.
