Stratos X MPX-K Gas Blowback Airsoft Submachine Gun (Black)

The Stratos X MPX-K Gas Blowback SMG (STR-MX-01) is a close-quarters monster — compact, aggressive, and built from the ground up to dominate tight environments. With no stock, a brutally short 350mm overall length, and a responsive gas blowback action based on the VFC system, this thing is designed for one thing: CQB supremacy. Whether you’re clearing tight corners, breaching entryways, or sprinting through urban layouts, the MPX-K gives you full-power realism in a platform that’s as lean as they come.

Externally, this submachine gun is all business. The CNC-machined aluminium upper receiver and matching M-LOK handguard scream quality, with precise fitment and minimal wobble. The finish is matte black and purposeful, giving the MPX-K that unmistakable modern PDW aesthetic. No stock means nothing to snag when you’re moving through doorways or around corners — just pure, unhindered mobility. And with a full-length top rail, you’ve still got plenty of space for optics, red dots, or even a compact magnifier if you’re feeling spicy.

Internally, it’s running on the tried and tested VFC gas blowback system — a staple for many high-end GBB platforms. That means reliable cycling, satisfying recoil, and a crisp trigger response every time you pull the trigger. With an output around 300 FPS on 0.20g BBs, it’s absolutely tailored for indoor and CQB fields. The included 30-round gas mag (aluminium construction) is sturdy, efficient, and balances realism with just enough ammo to keep you focused on shot placement and control.

The control scheme is fully ambidextrous, which isn’t just a nice-to-have — it’s essential in a gun like this. Whether you’re left-handed or regularly switch shoulders while cornering, you’ll appreciate the mirrored fire selector, mag release, and bolt catch. Reloads are fast and fluid, fire mode changes are snappy, and everything just works — exactly how it should under pressure. Steel components throughout the fire control group mean it can take a beating and keep going.

Up front, the M-LOK handguard offers just enough real estate for lights, angled grips, or lasers, without bulking up the profile. It’s all about sleek functionality — a proper PDW ethos. And since there's no external stock, this thing tucks right into your rig, your car, or a sling setup without fuss. It deploys quick, hits hard (in recoil and looks), and vanishes when you don’t need it.

If you're after an ultra-compact GBB that doesn't skimp on quality, realism, or functionality, the Stratos X MPX-K delivers. It’s not just a short rifle — it’s a purpose-built SMG platform for the player who wants speed, responsiveness, and no dead weight. And as always, if you spot it listed cheaper anywhere else — let us know and we’ll beat it.
