Specna Arms SA-F11 FLEX™ Gen.2 X-ASR offers even better performance and durability at an attractive price. The updated Gen.2 series is designed to take advantage of the manufacturer's experience and player feedback, making this electric gun an excellent choice for both beginners and experienced airsoft enthusiasts. The gun is equipped with the Gate X-ASR MOSFET system, which improves trigger response, extends component life, and allows for basic fault diagnosis using built-in indicator lights.
The FLEX™ series combines an affordable price, high-quality materials and innovative solutions, such as the ESA™ quick spring change system, which allows for quick spring changes without special tools.
The frame, forend, butt and pistol grip are made of nylon fiber reinforced polymer, making the structure lightweight yet durable. The barrel, flame arrester, charging handle and other critical parts are made of aluminum or ZnAl alloy, and steel pins, screws and other fasteners increase reliability. The upper part of the frame has an RIS/Picatinny rail for mounting accessories such as sights.
The heart of the gun is a reinforced Ver2 Æther™ gearbox, designed to withstand heavy use and deliver top-notch performance. It features a mainspring release, preload and AoE inspection windows, a reinforced front, inspection windows for easy preload, a trigger adjustment function, and alignment holes for the frame halves. The gearbox is pre-sized to withstand up to M140 springs. The mechanism features a sealed aluminum nozzle, steel gears, a polycarbonate piston with full metal teeth, a steel cut-off lever, 8mm plain bearings, and a precision shimmed drivetrain.
The gun features a 6.03 mm precision steel barrel for improved accuracy and range, as well as a Magnus™ TDC hop-up chamber and Helium™ Flat Hop rubber. Thanks to these, the bullets launch smoothly and fly accurately even at longer distances.
