SA-J82 CORE™ HAL ETU Gen. 2 - Black

The Specna Arms SA-J82 CORE™ HAL ETU Gen. 2 is part of the updated J-Series™ designed to offer airsoft players an exceptional out-of-the-box experience. With a perfect blend of affordability, durability, and modern electronics, this replica is ready to dominate the field.

Built from durable nylon-reinforced polymer, the replica remains lightweight (only 2.6 kg) without sacrificing structural integrity. Key external parts such as the barrel, gas block, and fire selector are made from aluminum and steel, ensuring excellent realism and durability.

Internally, it features a 6.03 mm precision barrel, 16:1 steel gearset, reinforced air-sealing components, and a TDC Magnus rotary hop-up unit – all of which contribute to improved accuracy and consistency during gameplay.

What truly sets this model apart is the integrated HAL™ ETU (Electronic Trigger Unit), offering:

• Magnetic trigger sensor with Hall effect

• Adjustable trigger sensitivity (5 levels)

• Adjustable pre-cocking (6 levels)

• Binary trigger and burst modes (3/5 round)

• Easy programming via trigger only

• Low-voltage battery warning

• Active braking for enhanced motor control

Thanks to the Quick Spring Change System, adjusting the FPS to meet field limits is fast and tool-free – no need to open the gearbox.

The SA-J80 is compatible with most AK magazines from Cyma, JG, E&L, and Bolt. The package includes 2 high-cap S-MAGs, M90 spare spring, cleaning rod, and a Tamiya-to-Deans adapter.

Note:
Before first use, calibrate the HAL™ unit by switching the fire selector to SAFE, connecting the battery, and holding the trigger for ~5 seconds until you hear a beep.
