Specna Arms SA-F03 FLEX Light Ops Stock HAL ETU Gen.2 AEG Assault Carbine - Olive

An electric carbine replica from the Flex series, constructed from metal, steel, and high-strength polymer. Outfitted with a HAL ETU electronic trigger unit, this system enables customizable adjustment of the replica’s settings to suit the operator’s preferences. Featuring an ESA quick spring change system, the replica, in its standard configuration, achieves a muzzle velocity of 390 FPS.

The receiver, front section in the M-LOK system, Light Ops Stock, and pistol grip are constructed from polymer reinforced with nylon fiber. Components including the barrel, flash hider, enlarged charging handle, dummy forward assist, and controls utilize aluminum and ZnAlu alloy. Steel is used for the screws, pins, ejection port, QD sling mount on the stock, and slide dummy. Markings and an individual serial number are present on the surface of the receiver. In addition to the M-LOK system, RIS rails in the 22 mm standard are located on the top and handguard, allowing for the installation of optics or additional accessories.

Factory installation features a rotating TDC Magnus Hop-Up chamber (Top Down Center) combined with a Helium Flat Hop bucking to provide consistent BB rotation. Precision shots are enhanced by the 6.03 mm tight bore barrel. A standard flash hider is attached to the outer barrel using a 14 mm counter-clockwise thread, making it compatible with most sound suppressors.
