Specna Arms SA-P20 Prime HAL ETU is a powerful electric gun designed specifically for demanding airsoft enthusiasts. The gun is equipped with an advanced HAL ETU unit and a high-torque 22TPA motor, which guarantees excellent response and reliable operation.
The frame is made of metal and finished with a Nano Coating known for its durability. The weapon has a 14 mm CCW external thread, which allows the installation of silencers and other accessories. RIS rails and folding sights increase the possibilities of use.
The weapon's innovative Aether™ gearbox, combined with a 6.02 mm precision steel barrel and Magnus™ TDC Hop-Up chamber, delivers excellent accuracy with every shot. The ESA2™ quick spring change system allows for tool-free spring changes, making it faster to adjust the weapon's power in the field.
Aether™ gearbox and internals
The Aether™ gearbox is designed as the heart of the Specna Arms Prime™ series, offering exceptional durability and versatile features for demanding players. The gearbox body is reinforced to withstand heavy use and high spring forces. This ensures reliability over long periods of use. The gearbox is designed with inspection windows that allow you to easily check the Angle of Engagement (AOE) adjustments and pre-tension without having to disassemble the entire system. The gearbox’s precise screw holes ensure proper alignment and balance of the parts, which improves service life and reliability. The gearbox is equipped with 8mm J-cage ball bearings (in the motor and piston gears) and 8mm plain bearings (in the sun gear), which ensure smooth and efficient operation at high rotational speeds. The anti-reversal release hole allows for easy spring release, preventing tension on the parts and preventing damage. The trigger tension adjustment screw allows for precise adjustment of trigger sensitivity, providing the player with optimal feel and response.
The Prime™ Series Aether™ Gearbox also features a completely redesigned pneumatic system for superior air tightness and pressure control. The steel cylinder is equipped with cooling fins that dissipate heat effectively and prevent material expansion during long firing cycles. The aluminum cylinder head with two O-rings ensures complete tightness and smooth cooperation with the cylinder. The sealed nozzle is specifically designed to be compatible with the MAGNUS™ hop-up chamber, which improves airflow control and delivery. The aluminum piston head with larger air intakes promotes consistent airflow and improves pressure control, and the steel-toothed polymer piston ensures reliable and durable operation. CNC-machined steel gears with a 16:1 gear ratio improve the speed and durability of the mechanism. The precision shimmed mechanism ensures that the gears are in perfect alignment, which improves the operation of the mechanism and increases the reliability and life of the weapon.
