Specna Arms F04-RL FLEX™ Gen. 2 – Digital precision in a lightweight format
Specna Arms SA-F04-RL FLEX™ Gen. 2 is designed for players who demand total control and maximum mobility. With integrated HAL™ electronics and a robust yet featherlight nylon-fiber construction, this rifle sets a new standard for modern airsoft AEGs.
HAL™ ETU Technology: Forget mechanical wear parts. The HAL™ system uses magnetic sensors to detect trigger pulls. This gives you access to advanced features such as binary trigger, 6 levels of pre-cocking, and active braking that stops the gears exactly where they should.
Important when powering on (Programming):
This rifle has an electronic trigger that must be activated when you connect the power. Do this by holding down the trigger for 5 seconds as soon as you plug in the battery, until you hear a few beeps.The weapon is now ready to use! If the rifle is stored without a battery for an extended period, it may reset—in that case, simply repeat this 5-second process. If you want more advanced settings, a separate programming card with simple instructions is included in the box.
Designed for speed
With a combat weight of just 2125g, the F04-RL is one of the lightest rifles on the market. The body is made from reinforced nylon fiber, while critical components such as the barrel, flash hider, and charging handle are made of metal. The minimalist "Light Ops" stock ensures a slim profile and good ergonomics when moving quickly between cover.
Internal upgrades you can feel
Inside, you'll find the reinforced Æther™ V2 gearbox with 8mm ball bearings and steel gears. To ensure maximum accuracy, the rifle is equipped with a TDC Magnus™ rotary hop-up and Helium™ Flat Hop rubber. This, combined with a 6.03mm precision barrel, giving you a trajectory that’s both stable and long, even in such a compact rifle.
ESA™ Quick Spring Change
ESA™ (Easy Spring Access) lets you adjust the rifle in seconds. Playing indoors? Install the included M90 spring for approx. 300 FPS. Heading out into the woods? Keep the standard spring for approx. 390 FPS. You don’t need to open the gearbox or use special tools to do the job.
