Specna Arms SA-J82 CORE™ HAL ETU Gen.2 is a modern AK-style electric airsoft gun for players who want a reliable and easily adjustable gun straight out of the box. The J-Series™ CORE Gen.2 combines a lightweight nylon-reinforced polymer body, upgraded internal parts and HAL™ electronics.
The SA-J82 body is made from reinforced polymer, keeping the overall weight moderate and making the gun easy to handle. The steel dust cover, fire selector and trigger guard add durability in high-stress areas. The side dovetail rail allows the use of AK-style optic mounts, and the folding stock makes the gun easier to transport and handle in tighter spaces.

HAL™ Trigger Calibration Before First Use
This airsoft gun is equipped with the HAL™ system, and the trigger must be activated before using the gun. Activation is done as follows:
Setup:
1. Turn the fire selector to the “SAFE” position.
2. Connect the battery to the gun.
3. Wait three (3) seconds until the gun emits a “beep” sound.
4. Pull and hold the trigger for approximately five (5) seconds until the gun emits a “beep” sound. This means that the HAL module activation has been successful.
