Cyma/EMG COLT.1004 M4 RIS 14.5 MWS Gas Blowback Rifle in Tactical Black

The Cyma/EMG COLT.1004 M4 RIS 14.5 MWS is a gas blowback airsoft rifle that effortlessly blends battlefield-proven design with the fierce performance of modern GBB tech. Officially licensed by Colt and built around the solid Tokyo Marui MWS platform, this airsoft gun is for players who want realism that hits hard—literally. It’s got the weight, recoil, and internals to back up its aggressive aesthetic, making it a favourite among milsim purists and tactical players alike.

From the moment you shoulder it, the weighty 2,240 grams of full-metal construction tells you this isn’t just another M4. The CNC-machined aluminium alloy externals feel sturdy and substantial, while the steel internal parts—bolt carrier, trigger, hammer, sear, and more—promise long-lasting, skirmish-hardened reliability. The classic 14.5-inch outer barrel and timeless M4 RIS handguard combination aren’t just there for show; they provide rock-solid realism and plenty of real estate for tactical accessories.

Powered by Cyma’s CGS gas blowback system, this rifle offers crisp cycling and a punchy recoil that’s more than just cosmetic. It’s based on the Tokyo Marui MWS platform, so it’s not only reliable but also compatible with a wide array of aftermarket upgrade parts. This means you can tune this airsoft rifle to your playstyle—whether you're fine-tuning it for DMR roles or going all out on CQB setups. The gas system is surprisingly efficient too, performing consistently even in cooler temps where lesser GBBRs begin to falter.

Shooting-wise, the COLT.1004 delivers a solid 300–350 FPS using 0.20g BBs, giving you effective mid-range accuracy and enough punch for outdoor fields. The adjustable hop-up allows you to dial in for range and consistency, making it a real contender for both woodland and urban skirmishes. Semi-auto and full-auto fire modes let you adapt to fast-paced firefights or controlled engagements.

Handling is just as thoughtful. The six-position stock gives you a comfortable length-of-pull no matter your size or loadout, easily adjustable between 745mm and 825mm. Up front, the RIS handguard gives you the freedom to bolt on foregrips, flashlights, lasers, or whatever tactical bling suits your mission. The 14mm CCW thread up front opens the door to suppressors and tracer units, making this a fantastic platform for both stealthy ops and night games.

One of the standout features of this airsoft gun is the 30-round gas magazine—solid, leak-free, and capable of handling the recoil demands of the blowback system. It feeds reliably and holds up well even under repeated use. Coupled with the full steel pins and internals, you’ve got a rifle that feels built for abuse, not just shelf display.

In short, the Cyma/EMG Colt M4RIS 14.5 MWS is a serious bit of kit. It balances realism and performance with upgrade flexibility, all while staying true to the legacy of one of the most iconic rifles in modern history. Whether you're building out a full milsim loadout or just want an airsoft rifle that handles like the real thing, this GBBR delivers in spades.
