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

The assault carbine electric replica from the second generation of the Flex line features a construction utilizing nylon fiber reinforced polymer for its body, M-LOK handguard, receiver extension, enhanced SF stock, and pistol grip. Components such as the barrel, flash hider, extended charging handle, dummy forward assist, and operating controls are crafted from aluminum alloy and ZnAl. Essential parts including screws, pins, the shell ejection port, QD sling mount, and dummy bolt utilize steel for durability. The body of the replica is marked with distinctive markings and a unique serial number.

mounting rail, extendable stock, 14 mm CCW thread

The top mounting rail enables the attachment of any optoelectronic accessory. In its standard configuration, the replica comes fitted with mechanical aiming aids, including a front sight and a peep sight. The adjustable stock with a non-slip butt plate provides customized length adjustment to suit the user's preferences. A flash hider mounted on a 14 mm left-hand thread offers straightforward replacement with a silencer or other compatible muzzle attachment.

Aether gearbox and rotary Hop-Up TDC Magnus chamber

At the heart of the replica lies the Aether gearbox featuring a reinforced structure, enabling the model to launch BBs at a velocity of 400 FPS. The gearbox offers:

  • main spring release functionality,
  • pre-cocking and AoE inspection ports,
  • strengthened front section,
  • inspection ports to facilitate easier shimming,
  • trigger adjustment capability,
  • screw holes for precise framework alignment,
  • compatibility with M140 springs.

The replica also incorporates a rotary Hop-Up TDC Magnus chamber for highly accurate adjustment. Performance is further enhanced by the Helium Flat Hop rubber, which substantially increases the stability of the BB's backspin.

ESA quick spring change system

The ESA rapid spring change system ensures quick and convenient power adjustment of the replica to comply with field regulations, without requiring specialized tools or a workshop. The set 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

MOSFET X-ASR system is integrated into the carbine, delivering enhanced protection for internal components, superior trigger response, increased durability of both electronics and battery, and enabling quick diagnosis of common issues within the replica through integrated signaling LEDs. Outfitted with a 6.03 mm precision barrel, the model is engineered for use with batteries featuring a Deans/T-Connect plug.
