Specna Arms SA-C17 CORE HAL ETU Gen.2 AEG Assault Carbine - Half-Tan

Electric-powered replica of an assault carbine from the CORE series, equipped with the HAL ETU system. Constructed from nylon-reinforced plastic, the body, receiver extension, SF stock, and pistol grip offer durability and lightweight handling. The barrel, front RIS rail, flash hider, enlarged charging handle, and tactical sling mount are crafted from metal. Essential components such as screws, pins, shell ejection window, and dummy bolt are produced from steel. Unique markings and a serial number distinguish the replica.

Durable construction, sighting devices

Outfitted with a split RIS 22 mm rear rail for optics installation, the model also features an adjustable stock, a front rail, and mechanical flip-up sights consisting of a front sight and a peep sight. The ergonomically shaped angled grip utilizing the M-LOK system, combined with a non-slip texture on the butt plate, guarantees both comfort and stability during shooting. A flash hider is threaded onto a 14 mm left-hand thread, enabling the attachment of a sound suppressor in its place.

Quick spring change system, TDC Hop-Up chamber

The enhanced quick spring replacement system enables rapid and efficient power adjustment of the replica to match the field’s requirements, all without specialised tools or workshop assistance. Outfitted with a rotating TDC Magnus (Top Down Center) Hop-Up chamber featuring a Helium rubber band, the model allows for highly precise and consistent tuning. An M90 spring is included, lowering the initial muzzle velocity to approximately 310 FPS, which is ideal for close-quarters and indoor operations.

Specna Arms Aether gearbox and its components

At the heart of the replica lies the Specna Arms Aether gearbox, enabling BBs to reach speeds of approximately 380 FPS. Components included are also compatible with M140 springs.

Features include:

  • an AntiReversal window
  • pre-cocking and AoE inspection windows
  • reinforced sections in high-stress zones
  • a motor gear inspection window
  • a trigger adjustment capability
  • alignment holes for the framework

Compatibility is ensured for Li-Po and LiFe batteries, utilizing a DEANS / T-connect connector.
