Aeroknox MWS Gas Blowback 10.5 M4 by Double Eagle (G103B)

Fully Licensed Aeroknox Aesthetics

If you want to stand out from the sea of standard mil-spec M4s, the Double Eagle Aeroknox MWS (G103B) is your perfect platform. Fully licensed by Aeroknox, it faithfully replicates the striking, aggressive lines of the real-steel AX//15 rifle. The CNC-machined aluminium alloy upper and lower receivers are flawlessly finished and proudly bear authentic laser-engraved Aeroknox trademarks. Paired with a sleek, modular M-LOK handguard and a modern flat-bow steel trigger, this rifle looks and feels like a top-tier, custom-built tactical firearm.

Tokyo Marui MWS Compatible

The true magic of this rifle lies under the hood. Double Eagle has engineered the G103B to utilise a high-quality clone of the industry-leading Tokyo Marui MWS ZET Gas Blowback System. This is a massive tactical advantage. Not only does it provide exceptional out-of-the-box gas efficiency and a deeply satisfying, crisp recoil impulse, but it also opens the door to the largest aftermarket upgrade ecosystem in the GBBR world. From precision inner barrels and upgraded hop-up buckings to reinforced nozzles and heavy recoil buffers, you have complete freedom to tune and upgrade your platform using standard TM-spec MWS parts.

Upgraded Steel Internals

Gas blowback rifles endure a significant amount of internal stress, which is why Double Eagle has reinforced the critical components right from the factory. The internal fire control group—including the trigger mechanism—is constructed from highly durable QPQ-finished steel. This ensures exceptional longevity and a buttery-smooth, consistent trigger break, allowing you to confidently fan the trigger on semi-automatic without fear of rapid wear and tear.

Versatile 10.5-Inch Profile

Finding the perfect balance between manoeuvrability and range is crucial. The 10.5-inch outer barrel configuration on the G103B strikes that balance perfectly. It is short enough to effortlessly clear tight indoor rooms, stairwells, and doorways, yet houses a long enough inner barrel to maintain excellent hop-up precision and range in open woodland environments. To keep the weapon comfortable during long patrols, it is fitted with a minimalist 3-position telescopic stock and an ergonomic pistol grip.
