Specna Arms X-series

The X-series is Specna Arms' answer to the general trend of AR-15-based machine gun replicas. Its compact size and top-notch workmanship make the replica an excellent choice for CQB games. In addition, the SA-FX01 airsoft gun is suitable as an effective sidearm for players with a sniper rifle or a powerful machine gun for close-quarters situations.

The SA-FX01 body is made of nylon fiber reinforced plastic, which makes the weapon very sturdy compared to traditional plastic-bodied airsoft weapons. The SA-FX01 is equipped with an M-LOK compatible foregrip, on the upper surface of which a standard RIS rail runs. At the end of the outer barrel of the weapon there are standard 14mm CCW threads to which a metal flame arrester is screwed. The flame arrester is easy to remove and replace with, for example, a light strip device or a silencer. On top of the weapon there are iron sights that fold out of the way if necessary.

The gun body and free-floating foregrip, buffer tube, Light Ops-type stock and pistol grip are made of nylon fiber-reinforced polymer. The barrel, flash suppressor, enlarged charging handle and shifters are made of aluminum alloy and ZnAl. All screws, pins, mounting flap and template are made of steel. The surface of the body is finished with the weapon's markings and serial number. The SA-FX01 airsoft gun is equipped with a minimalist Light Ops stock. The sliding Light Ops stock has rubber panels on both sides of the stock to ensure good grip.

One of the features of the SA-FX01 is the Quick Spring Exchange System, ESA™. This allows the weapon's power to be quickly and efficiently changed to suit the demands of the playing field without the need to disassemble the weapon.

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.
