Specna Arms SA-C12 CORE HAL ETU Gen.2 AEG Assault Carbine - Half-Tan

Constructed as an electric replica, the assault carbine from the CORE series features the advanced HAL ETU system. The body, receiver extension, SF stock, and pistol grip are produced from nylon fiber reinforced plastic to ensure durability and lightweight handling. The barrel, flash hider, charging handle, and tactical sling assembly are crafted from metal. Essential small parts, including screws, pins, ejection port, and dummy bolt, utilize steel for enhanced strength. Distinctive markings and a unique serial number have been applied to the replica for authenticity.

Durable construction, sighting devices

Fitted with a 22 mm RIS rail on the dust cover, the model allows for easy mounting of optics. It also features an adjustable stock and mechanical flip-up sights, including a front sight and a peep sight. An ergonomically shaped grip and a non-slip texture on the butt plate ensure comfort and steady handling during shooting. The flash hider is installed on a 14-millimeter left-hand thread, enabling the attachment of a sound suppressor if desired.

Quick spring replacement system, Hop-Up TDC chamber

The upgraded quick-change spring system enables rapid and efficient adjustment of the replica’s power to meet field requirements, eliminating the need for specialized equipment or a professional workshop. Equipped with a rotating Hop-Up TDC Magnus (Top Down Center) chamber featuring a Helium rubber band, this design offers precise and consistent tuning. The set comes with an M90 spring, which lowers the muzzle velocity to approximately 310 FPS, making the replica ideal for close-quarter or indoor engagements.

Gearbox Specna Arms Aether and its components

At the heart of the replica lies the Specna Arms Aether gearbox, delivering a muzzle velocity of approximately 380 FPS. Internal components are designed for compatibility with M140 springs. Engineered to support Li-Po and LiFe batteries, the system features a DEANS / T-connect connector.

  • AntiReversal release access port
