Specna Arms SA-FX01 Flex Gate X-ASR Gen.2 AEG Assault Carbine - Black

Experience an electric replica of the second-generation Flex series assault carbine, engineered with a reinforced Aether gearbox and a rotating TDC Magnus Hop-Up chamber. Out of the box, the carbine is fitted with a Gate X-ASR control system, providing customization to adapt the replica to individual operator requirements.

Durable construction

Metal is used for the outer barrel, flash hider, reloading handle, and manipulators. All screws, pins, the shell ejection port, and the dummy bolt are crafted from steel. The body, front, pistol grip, and stock with receiver extension are constructed from nylon fiber-reinforced polymer. Markings from Specna Arms and a serial number are featured on the replica.

RIS rails, Light Ops Stock

22 mm RIS top rail enables the attachment of any optoelectronic accessory. In its standard configuration, mechanical flip-up sighting devices are included, featuring both a front and rear sight. Additional tactical gear can be fitted using the free-float handguard equipped with short RIS rails.

Light Ops adjustable stock allows for precise regulation of the replica’s length to match the shooter’s physique and preferences. Non-slip texture is applied to both the pistol grip and butt plate. The flash hider attaches via the standard 14 mm left-hand thread.

Specna Arms Aether gearbox and its components

The model comes equipped with a rotating Hop-Up TDC Magnus (Top Down Center) chamber featuring a Helium rubber band, delivering precise and consistent adjustment. It incorporates a precision barrel with a 6.03 mm inner diameter, along with a polycarbonate piston boasting a full steel rail. The internal system utilizes 8 mm slide bearings for optimal performance.

At the core of the replica lies the Specna Arms Aether gearbox, enabling BB firing at a velocity of around 360 FPS. All internal components are also compatible with M140 springs. Designed for use with Li-Po and LiFe batteries, it features a DEANS / T-connect plug for convenient connection.

Features include:

  • An AntiReversal latch inspection window
  • Pcocking and AoE inspection ports
  • Extra reinforcement in high-stress zones
  • Motor gear inspection access
  • Trigger adjustment capability
  • Framework alignment holes

The carbine is outfitted with a MOSFET X-ASR system by the Polish company Gate. Replica is configured for battery connection via a Deans/T-Connect plug.

ESA quick spring change system

Equipped with the ESA quick spring change system, the replica allows for convenient adjustment of its performance to suit various gameplay styles. Included in the package is an M90 spring, enabling you to lower the default muzzle velocity of 360 FPS to approximately 300 FPS, making the replica well-suited for CQB scenarios.

    A really cool air rifle for less than 1000 PLN. Everything works, I've had it for almost a year and haven't encountered any issues. It shoots far and accurately, you can add a tracer and anything that's good for a 22mm RIS rail.
