Specna Arms SA-J83 CORE HAL ETU Gen. 2 AEG Assault Carbine - Black

Electric replica of an assault carbine from the CORE series, predominantly constructed from robust nylon fiber-reinforced polymer for reduced weight and reliable durability. Elements subjected to higher mechanical loads—such as the barrel mount, dummy slide, rear sight base with rear sight, stock mount, barrel, and front sight—are manufactured from a tough zinc and aluminum alloy. The bolt cover, safety lever, and trigger guard are crafted from steel.

Equipped with sighting devices and a dovetail mounting rail, the carbine supports the attachment of an optical sight. The adjustable stock provides the ability to tailor the replica’s length to individual user preferences. Both the pistol grip and the stock foot are designed with a non-slip texture for enhanced handling.

A brass, precision inner barrel with a 6.03 mm diameter delivers excellent accuracy and ensures consistent shot performance.

Featuring a quick spring change system, the replica enables rapid power adjustment to meet field regulations without requiring specialized tools or workshop access. Outfitted with a supplied M90 main spring, the replica is ideal for indoor skirmishes as well. Equipped with a rotary Hop-Up TDC Magnus (Top Down Center) chamber, the model offers precise and stable tuning.

At the heart of the replica lies a reinforced V3 gearbox, featuring:

• 16:1 gear ratio
• full steel jaw piston with 14.5 teeth
• piston head with a polymer seal
• cylinder head with a polymer seal
• aluminum alloy cylinder
