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

Electric replica of an assault carbine from the CORE line, equipped with the HAL ETU system. Constructed with a body, receiver extension, SF stock, and pistol grip made from nylon-reinforced polymer. The barrel, flash hider, charging handle, and tactical sling swivel are crafted from metal. Smaller components, including screws, pins, the ejection port, and the mock bolt carrier, are manufactured from steel. The replica is distinguished by unique markings and an individual serial number.

Durable construction, sighting devices

Featuring a 22 mm RIS rail on the receiver cover for optics attachment, an adjustable stock, and mechanical flip-up sights including a front sight and peep sight, this model is engineered for precision and versatility. The ergonomically contoured grip combined with a non-slip butt plate texture provides optimal comfort and stability during shooting. A flash hider mounted on a 14 mm left-hand thread enables easy installation of a sound suppressor as an alternative.

Quick spring change system, Hop-Up TDC chamber

A reinforced quick spring replacement system enables rapid and efficient power adjustment of the replica to meet the demands of the battlefield, all without requiring specialist tools or a dedicated workshop. Equipped with a rotating TDC Magnus (Top Down Center) Hop-Up chamber and a Helium rubber band, the model ensures highly precise and consistent tuning. The package contains an M90 spring, which lowers the initial muzzle velocity to approximately 310 FPS, making the replica ideal for short-distance engagements or indoor scenarios.

Specna Arms Aether gearbox and its components

At the heart of the replica lies the Specna Arms Aether gearbox, enabling BBs to reach velocities of around 380 FPS. Components utilized are also fully compatible with M140 springs. The replica is engineered for use with both Li-Po and LiFe batteries, featuring a DEANS / T-connect connector.

  • Anti Reversal release port
  • viewing ports for precocking and AoE
  • reinforcements located in high-stress zones
