CYMA CM.508 Gen 2 is an electric M4 S-System airsoft rifle with low weight, adjustable stock, and plenty of space for optics and other accessories. The body and large parts of the front are made of polymer, while the barrel, gearbox, and several stressed parts are made of metal. The characteristic S-System handguard features a continuous 20 mm Picatinny rail over both the receiver and handguard. The front also has shorter rails for accessories like foregrip, flashlight, or laser. Both the front and rear sights can be folded down so they don't obstruct your view when using a red dot sight or scope. The battery is placed inside the handguard, allowing the stock to remain slim and simple, while still being adjustable in length to suit the shooter and equipment.

GEN 2 Gearbox with MOSFET

The updated V2 GEN 2 gearbox is equipped with CYMA's MOSFET system, steel gears, 8 mm steel bushings, a sealed 20.96 mm nozzle, and a polymer piston with steel teeth. The MOSFET system reduces stress on the contacts and provides better trigger response. With the QSC system for quick spring change, the spring can be changed without having to dismantle the entire gearbox.

Rotary Hop-Up and 6.04 mm Inner Barrel

The adjustable rotary hop-up chamber makes it easy to fine-tune the hop-up for your chosen airsoft BB weight. The inner barrel is 385 mm long, made of brass, and has a diameter of 6.04 mm. The muzzle velocity is approximately 119 m/s, equivalent to 390 fps, with an energy of about 1.41 joules. The rate of fire is around 19 rounds per second with a suitable battery.

Battery and Accessories

The rifle can be used with a 7.4 V or 11.1 V LiPo battery with DEAN connector. The battery is placed in the front handguard. The muzzle features a 14 mm CCW thread for mounting a suppressor, tracer, or other compatible muzzle devices. Two hi-cap magazines with a capacity of about 300 6 mm airsoft BBs each are included. Battery and charger not included.
