Colt x EMG M4RIS 14.5 Gas Blowback Rifle by Cyma MWS (Black – COLT.1004)

The Colt x EMG M4RIS 14.5 Gas Blowback Rifle by Cyma MWS is an officially licensed M4RIS gas blowback rifle built for UK players who want authenticity alongside real field performance. Produced through a collaboration between Colt, EMG and Cyma’s CGS engineering, and licensed by Cybergun, it pairs a full-metal upper receiver with a lightweight, high-strength polymer lower, finished with genuine Colt trademarks for a realistic look and feel on the rail. Every detail, from the bronze-finished barrel to the markings on the receiver, is aimed at players who want their M4 platform GBBR to look and feel like the real thing without adding unnecessary weight.

Key Features

• Full-metal upper receiver with polymer lower – realistic weight and durability where it matters, without piling on unnecessary bulk.
• 14.5-inch barrel with bronze finish – a distinctive two-tone look that complements the Colt-licensed exterior.
• 4-position adjustable stock – quick length-of-pull changes for different body types and loadouts.
• Officially licensed EMG x Cyma x Colt collaboration – genuine Colt trademarks and markings, licensed by Cybergun.
• CGS (Cyma Gas System) – the gas blowback engine driving cycling and recoil feel on this GBBR.
• CGS quick-release rotary hop-up – tool-free hop-up adjustment for consistent shot placement.
• MWS-compatible platform – accepts MWS-spec magazines and internals, opening up a wide upgrade path.
• RIS picatinny handguard – full-length rail space for grips, lights, lasers and optics.

Real-World Use Cases

Milsim primary – the full-metal upper and Colt-licensed markings give this M4RIS the realistic look and heft milsim players want for a primary rifle across a long day in the field, and the 4-position adjustable stock makes it easy to dial in length-of-pull under load-bearing kit.

GBBR skirmish days at UK sites – gas blowback recoil and a genuine M4 profile make it a natural step up for players moving on from AEGs, provided your site’s FPS/joule limit is checked before you load a magazine.

Rail-mounted loadouts – the RIS picatinny handguard gives CQB and woodland players alike the space to run lights, grips and optics suited to indoor or outdoor games, without needing to remove the handguard to adjust the hop-up.

First GBBR after an AEG collection – the MWS-compatible platform means this is a sensible entry point into gas blowback for players who already own M4-pattern gear and want the recoil and cycling feel of a GBBR without starting from scratch.

Compatibility & Upgrades

Built to the MWS specification, this M4RIS accepts MWS-spec magazines and internal components, so it slots into the wider M4 GBBR ecosystem without major modification. The rotary hop-up is adjusted at the magwell rather than the handguard, so the RIS picatinny handguard stays in place for mounting a grip, light or optic while you dial it in. When you’re ready to push performance further, the platform accepts a tighter bore inner barrel for a flatter trajectory with heavier 0.28 g–0.30 g BBs, and it’s HPA-compatible if you later want to run an HPA engine instead of green gas or CO2 — get in touch with the team if you’d like advice on an HPA setup for this rifle.
