Colt M4A1 Block 2 FSP 12" | Rifle | AEG | Black | EMG / King Arms

The Colt M4A1 Block 2 FSP is a full-featured AEG (automatic electric gun) assault rifle on the M4/AR15 platform, constructed from a combination of materials — polymer and metal. Finished entirely in black, with a licensed Colt appearance and a Daniel Defense RIS II handguard straight out of the box, this is an airsoft replica that makes an impression the moment you pick it up.

Experience & handling

With a length of 88.0 cm, the Colt M4A1 Block 2 FSP sits in the all-round format — comfortable in the field without sacrificing manoeuvrability. The weight is 3.0 kg, which becomes noticeable during longer skirmish days, but also provides a solid and reassuring feel in the hands. The stock is adjustable, allowing you to quickly fit the replica to your own build or tactical vest. Thanks to the Picatinny rails surrounding the handguard, the replica is easy to equip with optics or accessories such as a foregrip, torch, or PEQ box. As an AEG, you need not worry about gas or reloading issues during a long skirmish day — a full battery will keep you going all day. One point to note: keep your barrel clean regularly, as a dirty barrel can lead to reduced accuracy.

What makes the Colt M4A1 Block 2 FSP 12" | Rifle | AEG | Black | EMG / King Arms special?

What sets this airsoft replica apart is the combination of a cast aluminium receiver with CNC finishing and stamped Colt trademarks, paired with a Daniel Defense licensed RIS II aluminium handguard. The gearbox is a fully metal V2 configuration with 8mm bearings and a quick-change spring guide, fully compatible with most Version 2 upgrades. Inside sits a neodymium high-torque motor with CNC-reinforced gears and a steel rack piston. The one-piece metal hop-up, integrated ambidextrous QD sling anchors, and inline MOSFET make this a technically well-equipped airsoft replica for players looking to progress or upgrade.
