CYMA M4A1 RIS Convertible 10.3" / 14.5" AEG Rifle (MOSFET - Black - CM002-GEN2)

Dominate tight indoor corridors and open outdoor skirmish fields with a single adaptable primary: the CYMA M4A1 RIS Convertible 10.3" / 14.5" AEG Rifle (MOSFET - Black - CM002-GEN2). Built on CYMA's robust Gen2 full-metal framework, this versatile M4 carbine gives airsoft players the flexibility to change operational barrel lengths on the fly while enjoying modern internal electronics.

Convertible Barrel System & Modular Quad RIS

The defining feature of the CM002-GEN2 is its convertible outer barrel assembly. By attaching or detaching the included metal outer barrel extension, players can configure the rifle as a tight 10.3-inch MK18-style CQB setup for room clearing or extend it to a classic 14.5-inch M4A1 carbine configuration for outdoor engagements. Surrounding the barrel is a heavy-duty metal Picatinny quad rail (RIS), providing standard mounting space across four sides for tactical flashlights, vertical foregrips, PEQ boxes, and bipods. The full-length upper receiver rail comes equipped with a removable A2-style carry handle sight, giving you the freedom to mount aftermarket red dot optics or scopes.

Upgraded Gen2 Gearbox & Integrated MOSFET

Internally, the CM002-GEN2 is powered by a reinforced metal Version 2 gearbox equipped with steel gears, high-torque motor, and a factory-installed electronic MOSFET unit. The MOSFET bypasses physical trigger contacts to eliminate electrical arcing, allowing safe operation with high-voltage LiPo batteries, improving trigger response time, and ensuring consistent rate-of-fire performance. Paired with a fully adjustable rotary hop-up unit, this AEG delivers exceptional shot-to-shot consistency and precise downrange trajectories.

Practical Applications & Real-World Use Cases

The modular barrel conversion, rugged full-metal frame, and MOSFET protection make the CYMA M4A1 RIS Convertible an ideal primary rifle across various game types:

• CQB to Outdoor Field Transitions: Easily convert from a compact 10.3" short-barrel setup for tight indoor arenas to a 14.5" length for long-range field skirmishes.

• Milsim Loadout Customization: Fully modular quad-rail interface lets you mount tactical weapon lights, laser aimers, and vertical grips tailored to your squad role.

• High-Volume LiPo Skirmishing: Factory-fitted MOSFET ensures snappy trigger response and protects internal circuitry during long tactical games.
