Sport Line Series

The Sport Line series is a CYMA product line designed to improve functionality and user comfort. The applied design solutions result in better balance, easier handling, and a more practical approach to everyday use. For the player, this means a replica that is simply more comfortable to operate — both during dynamic gameplay and extended sessions.

External build - what it means in practice

The replica is constructed from a combination of durable polymer and metal components, maintaining the solid character of the AK platform. The well-balanced construction allows the replica to sit naturally in the hands and reduces fatigue during prolonged use.

Solid fitment and the absence of noticeable play translate into better control over the replica during gameplay — both while firing and during dynamic movement.

The model features an individual serial number, making identification easier and highlighting its uniqueness.

Model U - ready for action and improved control

The CM.028 in version U is equipped with features that enhance control during use. The set includes a vertical grip, which improves stability while firing and makes handling easier in dynamic situations.

The front handguard with RIS rails allows for mounting additional accessories, enabling the user to tailor the replica to their preferences. The folding stock improves mobility, making the replica easier to handle in tight spaces and more convenient during transport.

Internal build - upgrades and player benefits

Internally, the replica follows the TM standard, ensuring wide compatibility with aftermarket parts as well as ease of servicing and further upgrades. The gearbox v3 is based on proven solutions such as 8 mm bushings and a sealed nozzle (19.70 mm), ensuring stable and consistent performance.

The GEN-2 version features a quick spring change system (QSC), allowing fast and convenient adjustment of the replica depending on the type of gameplay. For the player, this means greater flexibility and the ability to use one replica across different environments without switching platforms.

The MOSFET CYMA V3 system improves trigger response, increases electrical efficiency, and enhances overall operation smoothness — resulting in a more responsive and fluid shooting experience.

Performance and usability

The replica is equipped with an adjustable hop-up system and a 455 mm inner barrel, supporting accuracy and shot consistency at medium ranges. For the player, this means better control over BB trajectory and more predictable performance during gameplay.

Classic AK platform controls remain intuitive, making the replica suitable for both beginners and more experienced airsoft players.

Power and compatibility

The replica uses a T-connect connector and is compatible with 11.1V LiPo and 7.4V LiPo batteries. This allows the user to choose a setup that best fits their preferred performance. The battery is housed under the dust cover, making it easily accessible for quick replacement during gameplay.
