KWC M11 CO2 Airsoft Submachine Gun in Tactical Black

The KWC M11 CO2 Airsoft Submachine Gun delivers iconic looks, lightweight handling, and serious performance—all in a compact, skirmish-ready platform. Based on the legendary American SMG of the 1960s, this replica captures the raw, minimalist styling of the original while integrating modern airsoft performance via CO2 propulsion. With its high FPS, fixed hop-up, and foldable metal stock, the M11 is a serious contender for anyone wanting a punchy secondary or a compact primary for CQB fields.

Constructed with a tough ABS receiver and full-metal internals, this airsoft SMG finds a balance between durability and reduced carry weight. The ABS body makes it highly manoeuvrable, especially during fast-paced gameplay or tight corridor action. Meanwhile, the collapsible metal stock unfolds in two stages—a sliding rail and a bendable stock pad—giving you a solid shoulder rest for stabilised firing. Whether folded or extended, the M11 adapts quickly to your playstyle.

This isn’t just another SMG—it’s a powerhouse. Powered by a 12g CO2 capsule stored in the magazine, the KWC M11 fires at an impressive 460 FPS, giving it genuine outdoor capability and some serious range for such a compact platform. That energy is delivered directly into each shot with minimal waste, ensuring a flat trajectory and consistent velocity with every pull of the trigger.

Despite its compact design, the M11 is surprisingly accurate thanks to its built-in fixed hop-up. The system applies backspin to each BB, stabilising its flight path and helping to maintain tighter groupings over longer distances. It performs best with 0.20g or 0.25g BBs, making it suitable for both fast-paced CQB matches and mid-range field engagements where precision matters.

The magazine holds 26 rounds and features a solid metal construction that feeds reliably even during rapid firing. Reloads are quick, and the mag slides into the well with a satisfying click. The CO2 installation is simple using the provided hex key, and the gas efficiency is decent considering the high FPS output. As with all CO2 replicas, proper maintenance and lubrication are essential to keep things running smoothly.

Controls are minimal and intuitive. The M11 includes a trigger safety for added realism and to help prevent accidental firing between engagements. Its compact 260mm body (extended to 460mm with the stock deployed) makes it easy to sling or holster on a tactical rig, and its slim profile means it won’t get in the way during fast movement or transitions.

Whether you’re channeling that classic movie SMG vibe or just want something different from the usual pistol or rifle, the KWC M11 delivers. It’s fast, powerful, and compact, making it a fun and functional addition to any airsoft loadout.
