The SA-FX01 FLEX™ Submachine Airsoft Gun

Specna Arms introduces the FLEX™ line equipped with the HAL™ system. The HAL system enhances the functionality of the airsoft replica, allowing easy programming of features through the trigger and selector.

**HAL™ System Features:**

– Adjustable pre-cocking (6 levels)
– Programmable AUTO fire modes (full auto, semi-auto, 3-round burst, 5-round burst)
– Programmable SEMI fire modes (semi-auto, binary, AUG, sniper)
– Easy programming via the trigger
– Low battery warning
– Compatible with brushless motors

**Note:** The AUTO function begins with a 3-round burst before switching to full auto.

The SA-FX01 FLEX™ is Specna Arms’ response to the growing demand for AR-15-style submachine airsoft guns. With its compact size and strong performance, it’s ideal for CQB (close-quarters battle) matches and can also serve as a backup weapon for snipers or RKM operators. The use of nylon-fibre reinforcement makes the design more durable than other polymer-based models.

The SA-FX01 comes equipped with a front RIS rail, and the barrel is fitted with a standard flash hider. The top RIS rail features folding sights for easy targeting.

The replica’s body, free-float front, and slide are reinforced with nylon-fibre polymer, while the barrel, flash suppressor, enlarged charging handle, and controls are made from aluminum alloy. Steel is used for the screws, pins, sling mounts, and mock bolt lock. The barrel features markings and a serial number.

The SA-FX01 is equipped with the **Light Ops Stock**, a minimalist, extendable stock with non-slip rubber cheek panels and a curved rubber buttplate for comfortable shoulder support.

The replica includes the **ESA™ quick-change spring system**, which allows fast and easy power adjustments without the need for specialized tools or workshop access.
