G&G Armament CM18 GMS CQBR - M4 Combat Machine AEG

The Combat Machine line is G&G's mass-market entry into the AEG segment, designed to bring credible build quality to a budget price point. The CM18 GMS CQBR is the 10-inch-handguard version, putting it firmly in the CQB and short-range woodland category. The shorter handguard and full-length M-LOK rail give a clean front profile that works well for fast room-clearing and tight transitions.

The GMS MOSFET is what elevates the CM18 above the basic Combat Machine spec. The MOSFET protects the trigger contacts from the high-current spike that AEG motors generate, dramatically extending the lifespan of the trigger assembly. It also enables active braking on the motor, giving a sharper trigger response and reducing trigger lag on semi-auto. The ETU (Electronic Trigger Unit) adds programmable burst modes and a precise reset point.

Mechanically the CM18 uses G&G's reinforced V2 gearbox with a quick-change spring system: pop the rear pin, swap the spring to a different power level, reseat the pin, and you're done. Useful for UK skirmishers who might play at sites with different chrono limits, or for technicians tuning a build over time. The rifle ships with a 30-round mid-cap magazine.

Construction is reinforced polymer for the upper and lower receiver, keeping weight low at approximately 2.8kg unloaded. The handguard is aluminium with an M-LOK + Picatinny configuration. Stock is the GOS-V15 collapsible type with internal battery storage. Front and rear flip-up sights included.
