Description
Gen 2 FLEX M4 AEG Rifle with HAL ETU and Carry Handle Sights
The Specna Arms F10 FLEX Gen 2 HAL ETU M4 AEG Airsoft Rifle is a lightweight M4-style rifle built with upgraded Gen 2 internals, electronic trigger control, and a reinforced polymer body. The FLEX series is positioned as a step up from basic entry-level AEG rifles, giving players improved trigger response and stronger internal features without moving into a high-end price tier.
The HAL ETU uses magnetic trigger detection with Hall effect sensors, allowing adjustable trigger sensitivity, active brake, adjustable pre-cocking, binary trigger, and programmable fire modes. The rifle also includes a low battery alarm and brushless motor compatibility.
The F10 has a classic M4-style external layout with an AR-15-style foregrip, fixed front sight, and carry handle with integrated rear sight. This gives the rifle a familiar, straightforward sighting setup while keeping the Gen 2 FLEX internal upgrades found across the series.
The Magnus TDC rotary hop-up chamber and Helium Flat Hop bucking are included to support more stable hop adjustment and BB flight. The sealed aluminum nozzle, 6.03mm precision inner barrel, steel gears, 8mm bearings, and polycarbonate piston with full steel teeth give the rifle a stronger internal package than standard beginner AEGs.
