Cybergun COLT Licensed M4A1 Sportsline Carbine w/ Keymod Handguard (400 FPS)

Officially Licensed | Lightweight Polymer | TM-Compatible Gearbox

If you’re new to airsoft or looking for an affordable and dependable AEG, the Cybergun COLT M4A1 Sportsline Carbine is the perfect place to start. Built under full license from COLT Firearms, this electric airsoft rifle combines officially licensed trademarks with a tried-and-true Tokyo Marui Version 2 metal gearbox, making it a serious performer at a beginner-friendly price point.

Ultra-Lightweight, Yet Full-Featured

This M4A1 AEG features an ultra-lightweight polymer receiver and handguard, reducing fatigue for extended skirmishes without sacrificing durability. The modern Keymod handguard allows for flexible and modular attachment of grips, flashlights, lasers, and other tactical accessories, while the full-length Picatinny top rail makes it easy to mount optics or red dot sights. Flip-up front and rear iron sights come pre-installed and provide a backup aiming solution out of the box.

Internals Designed for Reliability & Upgrades

Don’t let the polymer build fool you—this rifle houses a Tokyo Marui-compatible Version 2 metal gearbox, a battle-proven internal platform with countless upgrade options. The quick-change spring guide lets you adjust your FPS to field or indoor limits without opening the entire gearbox—a rare feature at this price point.

Inside the gearbox, you’ll find durable steel gears, a long-type motor, and an adjustable hop-up system for fine-tuning your range and accuracy. Whether you’re shooting 380 or 400 FPS, this AEG delivers consistent and solid performance.

TM Spec Magazine Compatibility

The included 300-round hi-cap magazine is compatible with a wide range of standard M4/M16-style AEG magazines, including Matrix, Tokyo Marui, and most aftermarket brands. That means easy reloading and expanded magazine options as you upgrade your kit.

Ideal for Beginners & Budget Builds

Weighing in at just 4 pounds (1840g) and measuring 795mm to 875mm, this M4A1 platform is nimble and maneuverable—ideal for CQB scenarios, field games, or target practice. It’s wired to the stock and takes a 9.6v small butterfly battery (not included), using a Tamiya connector, which is widely compatible and easy to find.

The rifle also features semi-auto, full-auto, and safety firing modes, giving you tactical flexibility no matter your playstyle.
