Specna Arms SA-CX02 CORE HAL ETU Gen.2 AEG Assault Carbine - Black

The electric assault carbine replica in Half-Tan color belongs to the Core Gen. 2 series, which has undergone a redesign to provide enhanced performance straight out of the box. Outfitted with an ESA quick spring change system and a HAL ETU control module, users can easily tailor the replica's settings to their individual preferences. Featuring a Light Ops type stock, the replica utilizes construction components that are engineered with exceptional precision, ensuring reliable operation and smooth mechanism functionality.

Polymer body reinforced with nylon fiber, steel components

Constructed with a polymer reinforced with nylon fiber, the carbine's body, Free Float style front, receiver extension equipped with the Light Ops Stock, and pistol grip deliver durability and reliability. Steel components comprise the ejection port cover, dummy slide, along with all screws and pins. Markings and a serial number are present on the body for identification.

Light Ops Stock, ESA quick spring change system

Featuring a lightweight Light Ops Stock with an extendable construction, the replica provides enhanced comfort and adaptability. Rubber, non-slip inserts on both sides of the cheek pad deliver greater stability when aiming. The butt plate is outfitted with a curved rubber pad that rests securely against the shoulder. The inclusion of the ESA quick spring change system enables swift adjustments to the carbine's power to meet varying field requirements, eliminating the need for specialized tools.

Specna Arms Aether gearbox

At the heart of the replica is the Specna Arms Aether gearbox, delivering a muzzle velocity of 380 FPS when firing BBs. All internal components are compatible with M140 springs. Compatibility extends to both Li-Po and LiFe batteries equipped with DEANS / T-connect connectors.
