Airsoft Gun SA-F05-RL FLEX™ BLDC™ Light Ops Stock HAL ETU™ Gen. 2 – Black (Specna Arms)

The SA-F05-RL FLEX™ BLDC™ Light Ops Stock HAL ETU™ Gen. 2 from the FLEX™ Gen.2 series by Specna Arms is designed for immediate use without additional modifications and is suitable for competitive as well as intensive recreational airsoft. The construction combines nylon fiber-reinforced polymer with metal components in stressed areas such as the flash hider, outer barrel, bolt catch, and fire selector, ensuring high durability while maintaining low weight. The ergonomic Light Ops stock with anti-slip rubber elements and curved buttplate improves stability during shooting. The reinforced Æther™ V2 gearbox includes a quick main spring release and inspection windows for AoE control, while the ESA™ system allows rapid spring replacement without full disassembly. Accuracy is supported by a 6.03 mm inner barrel with a length of 320 mm, combined with the TDC Magnus™ rotary hop-up chamber and Helium™ Flat Hop Eraser system. A sealed aluminum nozzle ensures efficient air transfer. The HAL™ ETU Gen.2 electronic unit uses Hall sensors for magnetic trigger detection and offers active brake, binary mode, five trigger sensitivity levels, six pre-cocking levels, and programmable firing modes including an AUTO mode with an initial three-round burst followed by full automatic fire. The unit also monitors battery status and provides low voltage warning. The replica delivers approximately 380 FPS muzzle velocity, features a DEANS / T-connect connector with included Tamiya adapter, 14 mm CCW thread, and no blow back function. The adjustable length ranges from 760 to 850 mm with a weight of 2270 g. The package includes a 300 BB S-Mag Hi-Cap magazine, cleaning rod, hex key, Tamiya–Deans adapter, and additional M90 spring. Battery and charger are not included, and for first use the trigger must be held in SAFE mode for approximately 5 seconds after connecting the battery to initialize the HAL™ module.
