Specna Arms SA‑CH29 CORE™ Gen.2 HAL ETU

The Specna Arms Core Gen.2 carbines have been developed to deliver the best possible performance at an attractive price.

To achieve this, the Core Gen.2 carbines are equipped with, among other things:

• Helium™ Flat Hop rubber, which improves BB flight stability

• Aluminium, airtight sealed nozzle

• Ather™ Gearbox – reinforced housing (European Patent no. 015044865‑0001), equipped with:

  • Mainspring release function

  • Pre‑cocking and AoE inspection windows

  • Reinforced front section

  • Inspection windows for easy adjustment

  • Trigger adjustment function

  • Screw holes for gearbox alignment

  • Compatible with M140 springs

Construction

The body, slide, and battery compartment, as well as the pistol grip, are made of nylon-fiber reinforced polymer. Other components, such as the barrel, RIS front, flash hider, extended charging handle, sights, and tactical sling mount, are made of metal.

The replica is precisely manufactured; there is no play between the upper and lower frames. Using a lightweight polymer body reduces the weight, making this replica ideal for dynamic games and prolonged milsim scenarios. Furthermore, the fiberglass reinforcement makes the body stronger than standard polymer and even some metal bodies.
 

ESA™ Quick‑Change Spring System

The replica is equipped with the ESA™ quick-change spring system. This allows the replica’s power to be quickly and efficiently adjusted to the field conditions without the need for a workshop or specialized tools. All that is required is to unscrew the stock guide to access the spring – no need to remove or disassemble the gearbox.

The advantages of the ESA™ system are significant: in minimal time, the mainspring can be swapped, adjusting the muzzle velocity to the field, guaranteeing an ideal balance between performance and safety for all players.
