Specna Arms SA-F03 FLEX Gen.2 BLDC HAL ETU AEG Assault Carbine - Half-Tan

Electric replica of the SA-F03 assault carbine from the Flex Gen. 2 BLDC series, constructed from nylon-reinforced polymer combined with metal components. Outfitted with a HAL ETU control module, the carbine enables the customization of settings to suit user preferences. It features a brushless Specna Arms Dark Matter High Speed 27-35k motor as well as an ESA quick spring change system. All construction parts are meticulously aligned, ensuring reliable performance and smooth mechanism operation.

The body, M-LOK front, Light Ops Stock receiver extension, and pistol grip are constructed from nylon-reinforced polymer. Key components, including the flash hider, outer barrel, dummy bolt, ejection port cover, fire selector, bolt catch button, magazine release latch, QD sockets on the stock, pins, and charging handle, utilize metal construction. The body is adorned with markings and a unique serial number. Alongside the M-LOK system, RIS rails in the standard 22 mm width are installed on the upper and front sections of the handguard for mounting optics or additional gear.

Enlarged ambidextrous controls (selector and magazine release) and a bolt-catch mechanism are integrated into the model.

Equipped with a factory-installed rotating Hop-Up TDC Magnus chamber (Top Down Center) and a Helium Flat Hop bucking, the replica guarantees consistent BB backspin. Enhanced accuracy is provided by the precision 6.03 mm barrel. Fitted with a standard flash hider on a 14-mm left-hand thread, the outer barrel allows for the easy addition of a sound suppressor.

At the heart of the replica lies a V2 gearbox constructed on a robust Specna Arms Aether chassis, outfitted with:

• main spring quick-release mechanism
• inspection windows for pre-cocking and AoE adjustments
• reinforced front section
• inspection ports designed to facilitate smoother shimming
• trigger adjustment capability
• mounting holes for precise framework alignment with screws
• compatibility with M140 springs right out of the box

Internally, the gearbox houses parts including:

• 8 mm slide bearings
• hardened steel gears
• sealed aluminum nozzle

Fitted with a HAL ETU trigger control system, the model enables precise control over the replica’s functions and straightforward programming through the trigger and selector. The HAL system provides numerous functions for effortless adjustment to the operator's needs and enhanced safety during use, including:

• trigger recognition powered by magnetic sensors and the Hall effect
• active braking system
• binary firing mode
• customizable trigger sensitivity (5 settings ranging from 20% up to 100%)
• adjustable pre-cocking (6 selectable levels)
• programmable automatic firing modes: Full Auto, Semi, 3-round Burst, and 5-round Burst
• programmable semi-automatic firing modes: Semi, Binary, AUG, and Sniper
• intuitive programming via the trigger
• low battery warning indicator
• supports compatibility with brushless motor systems

The replica comes fitted from the factory with a premium brushless BLDC (Brushless Direct Current) motor, Specna Arms Dark Matter High Speed 27-35k, delivering enhanced power, rate of fire, efficiency, and reliability. Designed to handle exceptionally strong springs (up to M190), the motor boasts a high torque output (approximately 27,000–35,000 RPM).

Key features of the BLDC Specna Arms Dark Matter High Speed 27-35k brushless motor:

• no sparking during operation
• extended service life (no wear components)
• consistent performance at elevated RPM
• superior energy efficiency
• quiet running
• minimal heat buildup
• instantaneous trigger response
• maximum torque from startup
• permits the use of heavy springs without sacrificing efficiency or RPM

Featuring the ESA quick spring change system, the carbine enables rapid power adjustment to match game requirements, eliminating the need to disassemble the gearbox or use specialized tools. Out of the box, the replica comes with a factory spring that delivers an initial muzzle velocity of 410 FPS, along with an additional M90 spring.

Outfitted with a lightweight Light Ops Stock featuring a telescopic mechanism, the replica ensures optimal maneuverability. Rubber, anti-slip inserts on both sides of the cheek rest enhance stability during aimed shots. The buttplate has a curved rubber pad designed to comfortably conform to the shoulder.
