Specna Arms SA-C20-L CORE Light Ops Stock HAL ETU Gen.2 AEG Assault Carbine - Black

Electric replica of a carbine from the CORE series, equipped with the HAL ETU system. The body, receiver featuring a Light Ops Stock, and pistol grip are constructed with fiber enhanced by nylon reinforcement. Components subjected to increased strain, including the barrel, handguard, flash hider, enlarged charging handle, and tactical sling mount, are manufactured from metal. All screws, pins, the ejection port, and the dummy bolt utilize steel for extra durability.

Factory markings and an individual serial number are present on the body.

Durable construction, sighting devices

Equipped with a 22 mm RIS top rail for attaching optics, an adjustable stock, and mechanical flip-up sights including a front sight and peep sight, the model is designed for optimal performance. An ergonomically shaped grip and a non-slip texture on the butt pad provide both comfort and enhanced stability during shooting. A flash hider installed on a 14 mm left-hand thread enables the quick addition of a sound suppressor.

Quick spring change system, TDC Hop-Up chamber

The ESA Quick Spring Change System enables quick and efficient power adjustment of the replica to meet field requirements, all without the need for specialized tools or a workshop. Outfitted with a rotating Hop-Up TDC Magnus chamber featuring a Helium Flat Hop rubber, the model allows for precise and consistent tuning. Included in the set is an M90 type spring designed to lower initial velocity, ensuring the replica is well-suited for close-quarter or indoor missions.

Specna Arms Aether gearbox and its components

At the heart of the replica lies the Specna Arms Aether gearbox, delivering BB velocity of approximately 390 FPS. All installed components are also compatible with M140 springs. The design supports Li-Po and LiFe batteries fitted with a DEANS / T-connect connector.
