Experience & handling – Colt M4 URX4 Sportsline 11.5"

With a length of 73.0 to 81.5 cm, it sits in the all-round size category: compact enough for indoor use, yet perfectly suited for field play. At a weight of 2.18 kilograms, it is relatively light for a system with a full metal gearbox. The adjustable SOPMOD stock allows the model to be quickly adapted to different body positions and loadouts, and thanks to the M-LOK rails on the URX4 handguard, this model is easy to equip with optics and accessories. As an AEG (automatic electric gun), you are not dependent on gas, making it a hassle-free choice for long skirmish days — simply load a fresh battery and you are good to go. Do bear in mind that battery performance may decrease slightly during winter months, so always carry a spare battery on cold game days.

What makes the Colt M4 URX4 Sportsline 11.5" special?

What sets this model apart is the G3 gearbox with integrated MOSFET and microswitch trigger, delivering a sharper trigger response and protection when using higher-voltage batteries. The QD spring system makes spring changes straightforward without requiring full disassembly. The Colt licence is laser-engraved onto the receiver, and the receiver itself is constructed from high-strength nylon fibre-reinforced polymer for a lightweight yet solid build. The URX4 M-LOK handguard offers a full-length Picatinny top rail and M-LOK slots on both sides, plus QD sling swivel mounts on both the handguard and the stock.

A practical tip for every AEG (automatic electric gun): after playing, always switch to semi-automatic and fire one or two more shots to release tension on the spring in the gearbox — this extends the lifespan of your internal components.
