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

An electric assault carbine replica finished in Half-Tan, part of the Core Gen. 2 line, now updated to deliver superior out-of-the-box performance. Outfitted with an ESA quick spring replacement system and a HAL ETU control module, the replica enables complete adjustability to match user preferences. Enhanced with a Light Ops stock, the design incorporates structural components crafted with exceptional precision, resulting in outstanding performance and seamless mechanism operation.

Polymer body reinforced with nylon fiber, steel components

Constructed from nylon fiber reinforced polymer, the rifle body, Free Float front, receiver extension equipped with a Light Ops Stock, and pistol grip offer durability and strength. Steel components are utilized for the ejection port, dummy, as well as all screws and pins. Distinctive markings and a serial number are featured on the body.

Light Ops Stock, quick spring change ESA system

Fitted with a lightweight Light Ops Stock featuring a sliding mechanism, the replica includes non-slip rubber inserts on both sides of the cheek pad to enhance stability during targeting. The buttstock is equipped with a curved rubber pad that ensures a secure fit against the shoulder. Thanks to the ESA quick spring change system, power adjustment of the carbine to meet field requirements is possible without the need for specialized tools.

Specna Arms Aether gearbox

At the heart of the replica lies the Specna Arms Aether gearbox, delivering BBs at a velocity of 380 FPS. All internal components are compatible with M140 springs. Designed for optimal performance, the replica operates efficiently with Li-Po and LiFe batteries connected via a DEANS / T-connect plug.

  • a function for trigger adjustment
