Specna Arms SA-FX01 FLEX™ Gen.2 GATE X-ASR AEG - Black
The Specna Arms SA-FX01 FLEX™ Gen.2 is a compact AR-style AEG equipped with the GATE X-ASR MOSFET, Æther™ gearbox, Magnus™ TDC hop-up chamber and ESA™ quick-change spring system.
The SA-FX01 is part of the redesigned FLEX™ Gen.2 series, which combines a lightweight nylon-fibre-reinforced polymer construction with updated internal components. Its compact dimensions make the replica particularly suitable for CQB environments, while the adjustable stock allows the length to be adapted to the user and playing situation.
The free-float handguard features M-LOK mounting slots for compatible accessories. A continuous top RIS rail accommodates the included folding sights as well as compatible optics. The barrel ends in a flash hider mounted on a standard 14 mm CCW thread.
GATE X-ASR MOSFET
The factory-installed GATE X-ASR MOSFET protects the electrical system and improves trigger response compared with a conventional mechanical wiring setup. Integrated diagnostic LEDs also help identify basic electrical faults inside the replica.
The replica uses a DEANS / T-connect battery connector. A Small Tamiya to DEANS adapter is included in the package.
Æther™ reinforced gearbox
The SA-FX01 is built around the reinforced Æther™ V2 gearbox shell. Its design includes a reinforced front section, inspection windows, a mainspring-release function and provisions for checking pre-cocking and angle of engagement. The gearbox shell is designed to support springs up to M140, although the suitability of a spring always depends on the complete internal configuration.
Internal components include 8 mm plain bearings, a polymer piston with a full steel-tooth rack, an aluminium sealed nozzle and a 6.03 mm precision inner barrel.
Magnus™ TDC hop-up system
The rotary Magnus™ TDC hop-up chamber applies pressure directly from above, helping provide accurate and stable adjustment. It is paired with a Helium™ Flat Hop bucking nub to support a consistent BB trajectory.
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 field limits. An additional M90 spring is included.
Lightweight external construction
The receiver, M-LOK handguard, Light Ops stock and pistol grip are made from nylon-fibre-reinforced polymer. Aluminium and steel are used in selected external and functional components, including the barrel, flash hider, enlarged charging handle, controls, screws, pins and QD mounting components.
The extendable Light Ops stock features rubberised cheek-contact surfaces and a curved rubber butt pad for improved stability against the shoulder.
