The Specna Arms SA-PH23 Prime BLDC HAL ETU is a black, HK416-style electric airsoft rifle with a factory-installed brushless motor and programmable trigger unit. It suits players who value adjustable controls and a serviceable internal design. The metal receiver features a Nano Coating finish to help resist scratches, while the RAHG-style handguard provides mounting points for accessories.
The Dark Matter™ High Speed 27k brushless motor combines quick start-up with strong torque. Its brushless design eliminates carbon-brush wear and the associated maintenance. Working with CNC-machined steel gears in a 16:1 ratio, the motor supports responsive firing without requiring an aftermarket motor upgrade.
Inside the reinforced Æther™ V2 gearbox are a polymer piston with a full steel tooth rack, a steel cylinder, aluminium piston and cylinder heads, and a bearing spring guide. The gearbox uses 8 mm J-Cage ball bearings alongside bushings for the spur gear. Inspection windows make it easier to check pre-cocking and piston-to-gear engagement during maintenance.
The HAL™ ETU detects trigger movement magnetically using Hall sensors. You can choose from five trigger sensitivity levels and six pre-cocking levels. Programmable firing options include conventional semi-auto and full-auto, three- and five-round bursts, and binary mode. Settings are changed through the trigger without a separate programming device. Active braking and a low battery voltage alarm are also included.
A Magnus™ TDC hop-up chamber and Helium™ Flat Hop bucking provide fine adjustment of the BB’s flight path. They work with a 270 mm steel precision inner barrel with a 6.02 mm bore. The functional bolt catch makes accessing the hop-up adjustment easier, while the outer barrel’s 14 mm CCW thread accepts a compatible tracer unit or mock suppressor.
The ESA2™ quick spring change system allows tool-free spring replacement to adapt muzzle energy to field requirements. The package includes M90 and M135 spare springs, two 125-round S-MAG mid-cap magazines, a BB speedloader and a Mini Tamiya–Deans adapter. A battery and charger are not included and must be purchased separately.
