This isn’t just another SMG.
The Maruyama FMG-9 is one of the most unique gas blowback platforms to hit the airsoft market — a fully functional GBB submachine gun that folds down into a compact, discreet rectangular package and deploys in seconds.
Push, unfold, lock — and you’re ready to run.
Inspired by the legendary folding SMG concept, this airsoft version delivers the same jaw-dropping transformation factor with the added bonus of realistic gas blowback recoil and rapid-fire capability. It’s compact enough to stash, light enough to maneuver, and aggressive enough to dominate tight CQB environments.
Under the hood, the FMG-9 runs a proven gas system with crisp cycling and satisfying mechanical feedback. The extended Glock-style gas magazine keeps you fed in both semi and full-auto, while the adjustable hop-up lets you fine-tune your performance on the fly.
Whether you're building a low-profile kit, running a modern tactical loadout, or just want the coolest deploy animation on the field — this platform delivers.
