Specna Arms SA-F02 Flex Gate X-ASR Gen.2 AEG Assault Carbine - Black

An electric replica of an assault carbine from the second generation of the Flex series. The receiver, Keymod handguard, buffer tube, enlarged SF stock, and pistol grip are constructed from a nylon fiber reinforced polymer. The outer barrel, flash suppressor, extended charging handle, dummy forward assist, and the manipulators are produced from aluminum alloy and ZnAl. The screws, pins, shell ejection port cover, QD sling swivel mount, and dummy bolt are made using steel. Markings and a unique serial number are featured on the replica's body.

mounting rail, extendable stock, 14 mm CCW thread

Top mounting rail provides compatibility for attaching any optoelectronic accessory. By default, the rifle features mechanical aiming systems, including a front sight and a peep sight. An adjustable stock with a non-slip butt plate offers personalized length adjustment to suit individual user needs. A flash hider is installed on a 14 mm left-hand thread, making it quick and simple to swap for a suppressor or other compatible muzzle attachment.

Aether gearbox and rotary Hop-Up TDC Magnus chamber

At the heart of the replica lies the Aether gearbox with a reinforced chassis, delivering a BB muzzle velocity of 400 FPS. Outfitted with the following features:

  • main spring release capability
  • pre-cocking functionality and AoE (Angle of Engagement) checking windows
  • strengthened front section
  • inspection apertures designed to simplify shimming
  • adjustable trigger mechanism
  • screw ports for precise chassis alignment
  • fully compatible with M140 springs

The replica also incorporates a rotary Hop-Up TDC Magnus chamber for highly accurate tuning, while the inclusion of Helium Flat Hop rubber enhances backspin consistency and overall shot stability.

ESA quick spring change system

The ESA quick spring change system enables rapid adjustment of the replica's power to meet field regulations, eliminating the need for specialized tools or a workshop. The set also includes an M90 main spring, making the model ideal for indoor skirmishes.

MOSFET X-ASR system, 6.03 mm precision barrel, Deans/T-Connect plug

The carbine incorporates the MOSFET X-ASR system, providing enhanced protection for the replica's internal components, optimizing trigger response, extending the lifespan of both electronics and battery, and enabling basic malfunction diagnostics through integrated indicator LEDs. Outfitted with a 6.03 mm precision barrel, the replica is compatible with batteries using a Deans/T-Connect plug.
