Specna Arms SA-FX01 FLEX Gen.2 9" AEG Assault Rifle – Pink
Specna Arms presents the SA-FX01 FLEX Gen.2, an electrically powered AEG built around a reinforced V2 gearbox and fitted with a MOSFET/ETU unit for reliable trigger response and battery protection. The replica uses a 275-round mid-cap magazine, an adjustable hop-up chamber and a 235 mm inner barrel, delivering a muzzle velocity of 400 FPS suited to semi-automatic engagement at typical CQB distances. It is aimed at players who want a factory-ready carbine that can be tuned and maintained without specialist tools.
The FLEX Gen.2 line sits in the mid-tier of the Specna Arms range, combining the TDC Magnus rotary hop-up chamber, a Helium Flat Hop rubber ring and a sealed aluminium nozzle with the Ather reinforced gearbox shell. The HAL trigger system, based on magnetic Hall-effect sensors, adds programmable fire modes, adjustable trigger sensitivity and pre-cocking, active braking and a low-battery warning, and is compatible with brushless motors.
