SPECNA ARMS SA-J81 Core HAL ETU Gen2

Description

The SPECNA ARMS SA-J81 CORE™ HAL™ ETU Gen2 is a next-generation AK-style airsoft rifle from the CORE™ series, built for players who demand a reliable platform with advanced internals and modern technology—all at an affordable price. It combines the rugged AK aesthetics with state-of-the-art internals, including the HAL™ Electronic Trigger Unit (ETU) and ESA™ Quick Spring Change System.

This Gen2 version features a reinforced nylon polymer receiver, offering excellent durability while keeping the weight manageable. Metal parts include the barrel, fire selector, trigger guard, and internal gearbox components. The reinforced V3 gearbox is pre-upgraded with steel gears, 8mm bearings, and a full steel rack piston, making it ready for M140 springs out of the box.

The HAL™ ETU offers smart features like active braking, programmable fire modes (semi, full-auto, 3- or 5-round burst), adjustable trigger sensitivity, and low battery warning. It’s all configured simply via the trigger—no additional tools needed.

Externally, the SA-J81 replicates the classic AK profile, including a realistic fixed stock (for large batteries), traditional handguard, adjustable sights, and a functional hop-up system accessed via the AK-style charging lever. A 6.03 mm precision inner barrel ensures accurate and consistent shots.
