Description
Specna Arms SA-FX02 FLEX™ HAL ETU Gen.2 - Black
The Specna Arms SA-FX02 FLEX™ HAL ETU Gen.2 is a lightweight AR-style AEG equipped with the programmable HAL™ electronic trigger unit, Magnus™ TDC hop-up chamber, reinforced Æther™ V2 gearbox and ESA™ quick-change spring system.
The SA-FX02 belongs to the redesigned FLEX™ Gen.2 series, which brings modern electronics and upgraded internal components to an accessible price range. Compared with the shorter SA-FX01, the SA-FX02 features a longer front end and a 320 mm inner barrel while retaining a lightweight, nylon-fibre-reinforced polymer construction.
The free-float handguard features M-LOK mounting slots for compatible accessories, while the continuous top RIS rail accepts the included folding sights and compatible optics. The adjustable Light Ops Stock allows the overall length to be adapted to the user and playing situation.
Programmable HAL™ ETU
The HAL™ electronic trigger unit detects trigger movement using magnetic Hall-effect sensors instead of a conventional mechanical trigger switch. The system offers precise trigger detection and several programmable firing and response settings that can be configured 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.
This is the standard HAL™ ETU version and not the separate BLDC™ model equipped with a brushless motor.
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. The design 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 supports 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, muzzle device, 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.
