CYMA CM.507 Gen 2 is an electric M4 RIS airsoft rifle with classic AR15/M4 construction, adjustable stock, and a quad rail system at the front. The combination of a lightweight polymer body and selected metal parts gives a smooth rifle that is easy to handle during both fast-paced games and longer play days.
The quad RIS handguard features Picatinny rails for mounting, for example, a foregrip, flashlight, laser, or other airsoft accessories. The rifle comes with a classic M4 carry handle with integrated rear sight. The carry handle can easily be unscrewed, revealing a Picatinny rail for red dot sight, scope, or other optics (note that the front sight is fixed, so another sight may need to be mounted slightly higher so the front sight does not take up too much space in the sight picture).
The adjustable stock allows you to adapt the length to the shooter and equipment.

GEN 2 Gearbox with MOSFET

The updated V2 GEN 2 gearbox is equipped with CYMA’s MOSFET system for improved trigger response and more efficient power management to the motor. Internally, there are steel gears, 8 mm steel bushings, sealed 20.96 mm nozzle, type 2 cylinder, polymer piston with steel tooth, and a metal spring guide with bearing.
With the QSC quick spring change system, the spring can be replaced without having to dismantle the entire gearbox.

Rotary Hop-up and 6.04 mm Inner Barrel

The CM.507 has an adjustable rotary hop-up and a 385 mm long inner barrel with a 6.04 mm diameter. The combination provides good conditions for consistent trajectory and grouping with BB weights around 0.25–0.28 g.
The muzzle velocity is approximately 119 m/s, corresponding to 390 fps, with an impact energy of about 1.41 joules. With a suitable battery, the stated rate of fire is about 19 BBs per second.

Battery and Accessories

The rifle can be used with a 7.4 V or 11.1 V LiPo battery with DEAN connector. Split nunchuck batteries can be placed in the stock, while slim stick batteries can be placed in the buffer tube.
The muzzle has a 14 mm CCW thread for mounting a suppressor, tracer, and other compatible airsoft accessories. The rifle comes with two hi-cap magazines, each holding about 300 6 mm BBs.
