Specna Arms SA-C20 CORE HAL ETU Gen.2 AEG Assault Carbine - Olive

An electric assault carbine replica from the CORE series, equipped with a HAL ETU system. The body, receiver extension, SF stock, and pistol grip are constructed from nylon-reinforced polymer. The outer barrel, flash hider, charging handle, and tactical sling mount are manufactured from metal. Smaller components such as screws, pins, ejection port, and the mock bolt are produced from steel. Unique markings and an individual serial number are featured on the replica.

Fitted with side M-LOK rails and a top 22 mm RIS rail for mounting optics, the model features an adjustable stock as well as mechanical flip-up sights, including a front sight and peep sight. An ergonomically contoured grip and a non-slip textured butt plate provide enhanced comfort and stability during firing. The flash hider is secured on a 14 mm counterclockwise thread, offering compatibility for attaching a sound suppressor.

A reinforced quick spring exchange system enables rapid and efficient power adjustment of the replica, allowing users to meet field requirements without the use of specialized tools or a professional workshop. Outfitted with a rotary Hop-Up TDC Magnus chamber (Top Down Center) featuring Helium bucking, the model provides precision and stability in adjustment. Included in the set is an M90 type spring, which allows for lowering the initial velocity to approximately 370 FPS, making the replica ideal for close-quarters or indoor operations.

At the heart of the replica lies the Specna Arms Aether gearbox, designed to deliver BBs at a velocity of approximately 370 FPS. Components inside are compatible with M140 springs. Engineered for seamless operation with Li-Po and LiFe batteries, the setup features a DEANS / T-connect connector.
