Specna Arms SA-FX02 Flex HAL ETU AEG Submachine Gun with orange muzzle device - Half-Tan

An electric submachine gun replica constructed on the AR-15 platform, equipped with an orange muzzle device. Built from reinforced polymer enhanced with nylon fiber, the model delivers greater mechanical durability while retaining a lightweight profile. Ideally suited for CQB skirmishes or as a secondary weapon for snipers and support roles.

Nylon fiber body, Light Ops Stock

Constructed with a lightweight nylon fiber body and aluminum mechanical parts such as the outer barrel, enlarged charging handle, and operating elements, the replica ensures both durability and ease of handling. Components like pins, screws, belt loops, and the dummy bolt are crafted from steel. Outfitted with a Free Float front featuring the M-LOK system, a RIS rail with integrated sighting devices, and a Light Ops Stock designed with non-slip panels and a contoured recoil pad for enhanced comfort.

ESA quick spring replacement system, precision barrel

Within the internals, a rotating Hop-Up chamber is utilized alongside a precision barrel with a 6.03 mm diameter and a polycarbonate piston reinforced by a full steel rail. The internal system operates on 8 mm slide bearings. Featuring the ESA system, quick spring changes can be executed without requiring any tools, and the kit comes supplied with an extra M90 spring, enabling users to lower the replica’s muzzle velocity.

HAL ETU control system

Equipped with a HAL ETU control system, the replica enables customization of firing modes using both the trigger and selector. Operating on trigger position sensing that utilizes magnetic sensors and the Hall effect, the system offers integrated features such as:

  • active brake
  • binary trigger
  • adjustable trigger sensitivity across 5 levels (ranging from 20% to 100%)
  • adjustable pre-cocking with 6 different settings
