Specna Arms SA-C04 CORE™ HAL™ ETU black

Specna Arms SA-C04 CORE HAL ETU electric gun represents the latest version of the CORE series. CORE electric guns are composite-framed airsoft replicas equipped with exceptionally high-quality mechanisms in this price range. All parts of the gun that are subject to greater stress or have weaker material strength are made of metal. The gun's frame, buffer tube and SF-type crane stock that offers a large battery compartment, foregrip and pistol grip are made of nylon fiber-reinforced polymer plastic. The barrel, muzzle flash suppressor, charging handle and belt loops are made of metal.

The SA-C04 model has a metal RIS-compatible rail system on the foregrip, which allows for the attachment of various lights and foregrips to the weapon. There is also a RIS/Weaver-compatible rail on the top of the weapon for attaching optical sights.

The new generation CORE HAL ETU models feature an advanced electronics unit installed inside the gearbox, replacing the mechanical switch surfaces familiar from older models with a MOSFET circuit controlled by a HAL sensor.

All CORE series rifles also feature a true Quick Spring Exchange (ESA™), which allows the CORE series rifles to be used on all playing fields. The ESA™ quick spring exchange allows you to change the power of the weapon according to the rules of the playing field in a few minutes. M90 and M120 level springs are included. The lower power spring is great for indoor games and the higher power spring is great for outdoor games.

CORE airsoft guns are designed to work with LiIon, LiPo and LiFe batteries. The factory-installed spring provides a muzzle velocity of approximately ~116m/s with a 0.20g bullet. An M90-type spring is also included, which allows for a lower muzzle velocity of approximately ~90m/s with a 0.20g bullet, making the gun a perfect choice for indoor arenas as well.

Note: Calibrating the HAL™ trigger before use:

This airsoft gun is equipped with the HAL ™ system and before using the gun, the trigger must be activated. Activation is done as follows:

1. Turn the gun's fire selector to the "SAFE" position 2. Connect the battery to the gun 3. Wait three (3) seconds until the gun emits a "beep" sound. 4. Press the trigger all the way down for five (5) seconds until the gun emits a "beep" sound. This indicates that the trigger has been successfully activated.

HAL™ system features:

• Trigger detection using a magnetic sensor (Hall effect)
• Active brake
• Binary trigger
• Adjustable trigger sensitivity (5 levels, 20% - 100%)
• Adjustable piston pre-set (6 levels)
• Programmable fire selector
  • AUTO setting (full auto, semi, 3-shot burst, 5-shot burst)
  • SEMI setting (semi, binary, AUG, sniper)
• Easy programming with a trigger
• Low battery voltage warning
• Compatible with brushless motors

***The AUTO mode burst fire will first fire a 3-shot burst and then switch to full auto

CORE™ HAL ETU™ model series gearbox

The gearbox of the CORE™ HAL ETU™ model series has been completely redesigned and the corner rounding and geometry of the gearbox shells have been improved to increase the durability of the gearbox.

Gearbox features:

• Revised gearbox front end geometry
• 8 mm plain bearings
• Steel wheels
• Steel-toothed polycarbonate piston
• Steel switch lever
• The parts are designed to work with M140 springs (Atom Airsoft does not recommend using springs above 1.7J. We always recommend installing a Sorbothane during tuning so that the gearbox can withstand the increased strain even in the cold conditions of Finland )

Barrel and hop-up

• Rotary hop-up chamber
• 6.03 mm precision barrel (please use only high-quality airsoft bullets in the gun)

CORE quick spring replacement steps:

1. Remove the trailer hitch by pulling it out of place on the buffer tube.
