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

Electric replica of the SA-F03 assault carbine part of the Flex Gen. 2 BLDC series, featuring a construction of nylon-reinforced polymer combined with metal components. Outfitted with a HAL ETU electronic control unit, users can tailor the settings to individual preferences. The build includes a Specna Arms Dark Matter High Speed 27-35k brushless motor and the ESA quick spring replacement system. Precisely matched construction elements guarantee smooth performance and exceptional mechanical reliability.

Constructed from nylon-reinforced polymer, the body, M-LOK front, Light Ops Stock receiver extension, and pistol grip offer enhanced durability and lightweight performance. Metal components include the flash hider, outer barrel, dummy bolt, ejection port cover, fire selector, bolt catch button, magazine release latch, QD mounts on the stock, pins, and charging handle, ensuring structural strength and reliability. Markings and an individual serial number are present on the body for authenticity. Alongside the M-LOK system, 22 mm standard RIS rails are installed on the top and front of the handguard, facilitating the mounting of optics or other tactical accessories.

Enlarged, ambidextrous controls for the selector and magazine release, together with a functional bolt-catch mechanism, provide enhanced handling and operational versatility.

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. A 6.03 mm precision barrel enhances shot accuracy. The outer barrel features a standard flash hider on a 14-mm left-hand thread, making it compatible with sound suppressors.

At the heart of the replica lies a V2 gearbox, constructed on a reinforced Specna Arms Aether chassis, enhanced with the following features:

• main spring decompression capability
• inspection ports designed for pre-cocking adjustment and AoE tuning
• fortified front section
• inspection windows to simplify shimming
• adjustable trigger mechanism
• pre-made holes for screws to ensure precise framework alignment
• compatible with M140 springs

Inside, the mechanism is upgraded with components including:

• 8 mm sliding bushings
• hardened steel gears
• sealed aluminum air nozzle

Fitted with a HAL ETU trigger control system, the model enables straightforward function programming via the trigger and selector, enhancing the replica’s versatility. The HAL system brings a host of advanced features that facilitate seamless adaptation to the user's shooting preferences, while ensuring operational safety, such as:

• trigger activation through magnetic sensors and the Hall effect,
• active braking,
• binary firing mode,
• five-level adjustable trigger sensitivity (ranging from 20% to 100%),
• six-level customizable pre-cocking,
• programmable Auto fire modes (including Full Auto, Semi, 3-round Burst, and 5-round Burst),
• programmable Semi fire modes (options include Semi, Binary, AUG, and Sniper),
• user-friendly programming performed with the trigger,
• low battery warning function,
• support for brushless motor compatibility

Factory-issued with a premium-grade brushless BLDC motor (Brush Less Direct Current) Specna Arms Dark Matter High Speed 27-35k, the replica delivers enhanced power, superior rate of fire, outstanding reliability, and optimal efficiency. Engineered to handle exceptionally strong springs (up to M190), the motor provides high torque with an output of approximately 27,000-35,000 RPM.

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

• absence of sparking
• extended service life due to the lack of consumable parts
• consistent operation even at elevated RPM levels
• superior energy efficiency
• reduced operational noise
• minimal heat buildup
• instantaneous trigger reaction
• maximum torque from the moment of activation
• enables the application of heavy-duty springs while maintaining efficiency and RPM

Featuring the ESA quick spring change system, the carbine enables rapid adjustment of power to match game requirements without needing to dismantle the gearbox or use specialized tools. Supplied with a factory spring achieving an initial velocity of 410 FPS, the replica also includes an additional M90 spring.

Outfitted with a lightweight Light Ops Stock featuring a telescopic construction, the replica ensures adaptability and comfort. Rubber, anti-slip inserts on both sides of the cheek rest enhance stability during aiming. The buttplate comes with a curved rubber pad that provides a secure and comfortable fit against the shoulder.
