Specna Arms SA-C07 CORE HAL ETU Gen.2 AEG Assault Carbine - Black

Second-generation electric replica of the CORE series assault carbine. Outfitted with a reinforced Aether gearbox and a rotating TDC Magnus Hop-Up chamber, the model ensures durability and precision. Default configuration includes a HAL ETU control system, which enables users to customize the replica's settings to suit their individual preferences.

Durable construction, folding sighting devices, KeyMod front grip

Constructed from a blend of highly durable metal, steel, and plastic, the replica features a robust build designed for resilience against damage. The body, SF-type stock with receiver extension, and pistol grip are crafted from tough polymer materials. All screws, pins, the shell ejection port, and the dummy bolt are manufactured from steel, while the remaining elements utilize metal construction. Outfitted with 22 mm RIS rails, the platform facilitates the attachment of any optoelectronic accessories. In its standard configuration, the replica comes fitted with mechanical flip-up sighting devices, including a front sight and a peep sight. Additional tactical gear can be mounted through the KeyMod front grip. The included short rail segments further enable the installation of any RIS 22 mm compatible accessories to the grip.

Adjustable stock, 14 mm CCW thread

Equipped with an adjustable SF stock, the replica's length can be tailored to fit the operator's physique and personal preferences. Enhanced control is provided by the non-slip texture on both the pistol grip and butt plate. A standard 14 mm left-hand thread allows for easy attachment of the muzzle device.

ESA quick spring change system, rotary Hop-Up chamber

Featuring a quick spring change system (ESA), the model offers the convenience of easily adjusting the power of the replica to meet battlefield requirements, all without the need for specialized tools or workshop access. Factory settings enable the replica to achieve a muzzle velocity of 390 FPS. Thanks to the supplied M90 main spring, the replica is well-suited for indoor skirmishes. A rotating TDC Magnus Hop-Up chamber equipped with a Helium rubber band delivers excellent BB stability.

Specna Arms Aether Gearbox

At the heart of the replica is the V2 gearbox, constructed on the reinforced chassis of the Specna Arms Aether (protected by European Patent No. 015044865-0001). The gearbox comes outfitted with the following features:

  • main spring decompression mechanism
  • pre-cocking and AoE inspection ports
  • strengthened gearbox front
  • inspection ports designed for straightforward shimming adjustments
  • adjustable trigger system
