SA-J83 CORE™ HAL ETU Gen. 2 - Black

Specna Arms SA-J83 CORE™ Gen. 2 is a modern electric airsoft carbine inspired by the famous AK platform. It is suitable for players looking for a high-quality and compact replica at a reasonable price. Thanks to its reinforced polymer body, the rifle is lightweight yet highly durable. Critical components are made of metal or steel, ensuring longer lifespan and a realistic appearance.

A key advantage is the HAL™ ETU electronic unit, which offers advanced features such as programmable fire modes (e.g., 3- or 5-round burst), binary trigger, active brake, and five-stage trigger sensitivity adjustment. All settings can be easily programmed directly via the trigger—no need to connect external devices.

Inside, you’ll find a 6.03 mm precision brass barrel, a rotary Magnus TDC Hop-Up chamber, a reinforced ORION™ gearbox with a 16:1 gear ratio, a full steel piston, and an aluminum cylinder. Thanks to the quick spring change system, the rifle's power can be easily adjusted without opening the gearbox.

The replica is ready for LiPo batteries and provides enough space for a stick-type battery under the dust cover.
