Gen.2 – improved version of the popular FLEX™ series
The Specna Arms F03 FLEX™ Gen.2 is a further development of the renowned FLEX™ series, created to provide beginners and advanced players with an even better experience. The Gen.2 models come with upgraded internals, higher precision and better electronics – all wrapped in a lightweight and sturdy M4/M15 platform. This is one of the best beginner options on the market, where you get a lot of value for your money.
Equipped with GATE X-ASR MOSFET
The rifle is factory-fitted with GATE X-ASR, a MOSFET system that provides faster trigger response, protects the electronics, and extends the life of both the motor and battery. The built-in LED error diagnostics make it easier to identify problems – perfect for players who want a safe and user-friendly start.
Improved internal components
- TDC Magnus™ Rotary Hop-Up – stable and precise ball trajectory (patent protected).
- Æther™ V2 gearbox – reinforced frame with inspection windows, ready for M140 springs.
- Helium™ Flat Hop Eraser – better stability over longer distances.
- Precision barrel (6.03mm) for higher accuracy.
- Quick Spring Change ESA™ – change springs and adjust force without tools.
Adapted both indoors and outdoors
The F03 delivers approximately 400 FPS with the standard spring, which is perfect for outdoor play. With the included M90 spring, you can easily reduce the muzzle velocity to approximately 300 FPS, making the rifle ready for CQB and indoor ranges. This makes the model very flexible and adaptable to different game areas.
Built for comfort and durability
- Body, stock, pistol grip and M-LOK handguard in nylon-reinforced polymer – lightweight and durable.
- Outer barrel, flash suppressor, sights and charging handle in aluminum/ZnAl alloy.
- Critical parts in steel for extra durability.
- Lightweight construction (2260g) – ideal for dynamic gameplay and CQB.
