Specna Arms SA-F03 Flex Gate X-ASR Gen.2 AEG Assault Carbine - Black

Electric-powered replica of the second-generation Flex series assault carbine. The body, M-LOK front handguard, receiver extension, enlarged SF-type stock, and pistol grip are constructed from nylon fiber-reinforced polymer. The barrel, flash hider, enlarged charging handle, dummy forward assist, and controls feature aluminum alloy and ZnAl components. Steel is used for the screws, pins, ejection port, QD sling mount, and dummy bolt. The body of the replica features markings and a unique serial number.

mounting rail, extendable flask, 14 mm CCW thread

The dorsal mounting rail provides the option to attach any type of optoelectronic accessory. In the standard configuration, mechanical sighting systems are included in the form of a front sight and peep sight. An adjustable stock with a non-slip butt plate ensures the replica’s length can be personalized to suit user preferences. The flash hider threaded on a 14-millimeter left-hand thread enables straightforward replacement with a sound suppressor or other compatible muzzle accessories.

Aether gearbox and rotary Hop-Up chamber TDC Magnus

At the heart of the replica lies the Aether gearbox featuring a reinforced framework, enabling the model to achieve a firing velocity of 400 FPS with BBs. The system also includes:

  • a mainspring de-tensioning function
  • pre-cocking and AoE inspection ports
  • a reinforced front section
  • inspection ports for hassle-free priming
  • an adjustable trigger feature
  • screw holes for precise framework alignment
  • compatibility with M140 springs

Additionally, the replica comes with a rotary Hop-Up chamber TDC Magnus for pinpoint adjustment. The Helium Flat Hop Eraser enhances shot stability and reduces BB drop.

ESA quick spring change system

The ESA quick-change spring system enables rapid and efficient adjustment of the replica’s power to meet field requirements, with no need for specialized tools or a workshop. Outfitted with an M90 mainspring, this model is equally well-suited for indoor skirmishes.

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

MOSFET X-ASR is installed in the carbine, providing reliable protection for the replica's internal components, enhancing both trigger response and the longevity of the electronics and battery. Built-in indicator LEDs also facilitate quick diagnostics of basic internal malfunctions. The model features a 6.03 mm precision inner barrel and accommodates batteries equipped with a Deans/T-Connect connector.
