Dominate the field with the ICS CXP-MMR M4 Airsoft AEG Carbine, a full-metal, performance-driven rifle that combines battle-tested durability with cutting-edge internals. Whether you're a seasoned milsim player or weekend warrior, this carbine delivers unmatched reliability and modularity straight out of the box.

Rugged Full-Metal Construction

Crafted with a CNC-machined aluminum upper receiver and a forged lower receiver, the ICS CXP-MMR exudes strength and precision. Both receivers feature laser-engraved ICS trademarks, adding a professional finish that matches the internal performance. The full-metal M-LOK handguard is compatible with all standard M-LOK accessories, giving you limitless options to customize your loadout with grips, lights, lasers, and more.

ICS’s Iconic Split Gearbox System

At the core of this rifle is ICS’s renowned split gearbox system, designed to simplify maintenance and upgrades while replicating the upper/lower receiver feel of a real AR platform. The gearbox is wired with an inline MOSFET to enhance trigger response, protect electrical components, and ensure consistent power delivery shot after shot.

The gearbox is paired with an M120 spring, delivering high-powered, field-ready performance with FPS in the range of 421–441 (measured with 0.20g BBs). It’s a fantastic choice for outdoor games, longer engagements, and players looking for precision and range.

Enhanced Ergonomics & Tactical Design

The ergonomic low-profile pistol grip gives you superior control and comfort, especially during extended engagements. The MTR-S1 adjustable stock not only provides multiple length-of-pull settings to fit any shooter but also includes large battery storage space, making it ideal for LiPo users and extended play. This rifle is rear-wired to the stock and comes ready for a 9.6v small butterfly battery (battery not included).

The 375mm inner barrel provides excellent accuracy, while the adjustable hop-up unit lets you fine-tune trajectory for various BB weights and distances.

Field-Ready Accessories & Compatibility

Out of the box, the CXP-MMR includes ICS CFS flip-up front and rear sights, allowing for fast target acquisition or backup sighting when using optics. With a 14mm negative thread direction, it’s easy to mount a suppressor or tracer unit to enhance your setup.

The 300-round high-cap magazine is compatible with popular brands like Matrix, G&G, and Tokyo Marui, ensuring you’ll never run short on ammo options. Fire modes include semi-auto, full-auto, and safe.
