Specna Arms MK-18 SA-F19 Flex HAL ETU Gen. 2 Assault Rifle AEG - Half Tan

An electric AEG assault rifle replica in a Half-Tan colour scheme, part of the Flex Gen.2 series and equipped with licensed Daniel Defense markings and an individual serial number. Control is handled by the electronic HAL unit, which allows adjustment of the replica's operating parameters and programming of trigger functions. The design is complemented by a reinforced Æther gearbox, a TDC Magnus Hop-Up chamber, and the ESA quick spring change system.

Polymer body, metal structural elements

The body is made of nylon fibre-reinforced polymer, which helps reduce weight while maintaining resistance to intensive use. The outer barrel, muzzle device, charging handle, controls, dummy forward assist, ejection port cover, pins, and screws are made of metal. Inside, there is a 6.03 mm precision inner barrel. The replica is equipped with an adjustable SF-type stock with a rubber recoil pad that provides more stable shoulder support.

22 mm RIS rail, sighting devices

On the top of the replica there is a 22 mm RIS rail that allows the installation of additional accessories such as an optoelectronic sight. It comes factory-fitted with mechanical sighting devices in the form of a front sight and peep sight. The flash hider is mounted on a 14 mm CCW left-hand thread, so it can be replaced with a compatible muzzle device.

Æther gearbox

The replica features a reinforced Æther gearbox. The muzzle velocity is approximately 380 FPS. The gearbox design includes:

  • main spring release function
  • inspection window for pre-cocking and AoE
  • reinforced front
  • inspection windows facilitating shimming
  • trigger adjustment function
  • holes enabling framework position alignment
  • adapted for use with M140 springs
  • 8 mm plain bearings
  • steel gears
  • polycarbonate piston with a full steel rack

TDC Magnus Hop-Up, ESA system

The replica allows single, adjustable, and continuous fire. It uses a Hop-Up TDC Magnus Top Down Center rotary chamber, which enables precise and stable adjustment of bucking pressure, along with a Helium Flat Hop bucking that supports the stability of the BBs flight path. The model does not have a Blow Back system. The ESA quick spring change system allows the replica's characteristics to be adjusted without disassembling the entire gearbox.

HAL electronic control unit

The electronic HAL unit uses magnetic sensors and the Hall effect to detect trigger operation. It allows adjustment of the replica's operating parameters and function programming via the trigger:

  • trigger detection based on magnetic sensors and the Hall effect
  • active brake
  • binary trigger
  • adjustable trigger sensitivity in 5 levels from 20 to 100%
  • adjustable pre-cocking in 6 levels
  • programmable AUTO modes: full auto, semi, 3-round burst, 5-round burst
  • programmable SEMI modes: semi, binary, AUG, sniper
  • programming via the trigger
  • low battery charge alarm
  • compatible with brushless motors

A Deans/T-Connect connector is used to connect the battery.

Hi-Cap magazine

The set includes a Hi-Cap type magazine designed to feed the replica with 6 mm BBs.
