Specna Arms SA-FX01 FLEX™ HAL ETU Gen.2 - Black
The Specna Arms SA-FX01 FLEX™ HAL ETU Gen.2 is a compact and lightweight AR-style AEG equipped with the programmable HAL™ electronic trigger unit, Magnus™ TDC hop-up chamber, reinforced Æther™ gearbox and ESA™ quick-change spring system.
The SA-FX01 belongs to the redesigned FLEX™ Gen.2 series, combining an accessible price point with features normally associated with more advanced airsoft guns. Its compact construction and approximately 2,000 g weight make it particularly suitable for CQB, fast-paced gameplay and players looking for an easily manoeuvrable primary weapon.
The free-float handguard features M-LOK mounting slots for compatible accessories. A continuous top RIS rail accommodates the included folding sights and compatible optics. The adjustable Light Ops Stock allows the overall length to be changed between approximately 670 and 760 mm.
Programmable HAL™ ETU
The HAL™ electronic trigger unit uses magnetic Hall-effect sensors to detect trigger movement without a conventional mechanical trigger switch. The system provides precise trigger detection and allows several firing and response settings to be programmed directly through the trigger.
-
Adjustable trigger sensitivity: five levels from 20 to 100%
-
Adjustable pre-cocking: six levels
- Active Brake
- Binary trigger mode
-
Programmable AUTO selector modes: full auto, semi-automatic, three-round burst or five-round burst
-
Programmable SEMI selector modes: semi-automatic, binary, AUG or sniper mode
- Low-battery warning
- Compatibility with brushless motors
In the HAL™ AUG mode, pulling the trigger fires a three-round burst. Keeping the trigger pressed after the burst continues the firing cycle in full auto.
Reinforced Æther™ V2 gearbox
The Æther™ V2 gearbox shell features a reinforced front section, inspection windows and provisions for checking pre-cocking and angle of engagement. It also includes a mainspring-release function, trigger adjustment and screw holes that assist with gearbox-shell alignment.
The gearbox shell is designed to support springs up to M140. The suitability of a stronger spring depends on the complete internal configuration and the permitted muzzle-energy limit of the playing field.
Updated internal components
- 8 mm plain bearings
- Steel gears
- Polycarbonate piston with a full steel-tooth rack
- Sealed aluminium nozzle
- 6.03 mm precision inner barrel
- Magnus™ rotary TDC hop-up chamber
- Helium™ Flat Hop nub
The Magnus™ TDC hop-up chamber applies pressure directly from above, allowing accurate and stable adjustment. Together with the Helium™ Flat Hop nub and 6.03 mm precision inner barrel, it helps produce a consistent BB trajectory in the factory configuration.
ESA™ quick-change spring system
The ESA™ quick-change spring system allows the mainspring to be replaced without opening the gearbox. This makes it easier to adapt the muzzle velocity to different field limits. An additional M90 spring is included.
Lightweight reinforced construction
The receiver, free-float M-LOK handguard, pistol grip and Light Ops Stock are made from nylon-fibre-reinforced polymer. The barrel, flash hider, enlarged charging handle and selected controls are made from aluminium and zinc alloy, while screws, pins, ejection-port components and the mock bolt are made from steel.
The adjustable Light Ops Stock features non-slip rubber cheek-contact surfaces and a curved rubber butt pad that sits securely against the shoulder. The receiver includes manufacturer markings and an individual serial number.
