GFG42 carbine replica (ASCU Gen.4 version)

GFG42 is made from metal and durable polymer. The stock pipe, outer barrel, RIS rails, iron sights and all sorts of small elements such as trigger, magazine release button or fire mode selector are made from metal. The body, stock and profiled pistol grip as well as RIS rails linings are made from polymer.

The replica features a top, 22mm RIS rail and a set of front RIS rails as well as a collapsible stock. Due to collapsible stock with a pad with anti-slip texture it is possible to adjust the length of the stock to the body type and user’s preference. The replica has a 14mm, left-hand thread.

The battery included in the set is stored in the stock. The replica has a mini connector and MOSFET module. Reinforced TORQUE-UP gears, metal spring slide, reinforced gearbox skeleton and reinforced piston with metal teeth increase the longevity of the replica. The motor with increased torque together with low resistance wires provide increased efficiency.

The ASCU is a two-part electronic module ( the control module and the sensor module ) which, upon being installed in the Airsoft replicas, significantly improve their operation. The traditional joint module was replaced with a sensor module which monitors the actual position of the piston thread-wheel, the firing mode selector lever and the trigger. The gathered information is sent to the control module – in which the software located in the processor analyzes it and controls the replica’s motor with the use of the MOSFET active break.

ASCU Gen. 4 includes the following upgrades: 

1. New MosFet transistors with 16 times less resistance, resulting in to faster cycle, better active brake, more shots per battery charge and less heat.
2. New very strong trigger switch.
3. New reinforced design with full polymer encasing.
4. Better short-circuit protection.
5. Easier installation.
6. Updated software with easier programing (accidental hop-up program activation is impossible).
7. Improved cut-off lever.
8. Improved selector plate.
9. Fits all standard and reinforced version 2 gearboxes.
10. 3 year world wide warranty.

The ASCU improves the operation of a V.3 gearbox and makes that the replica equals the more expensive replicas and the more sophisticated PTW class replicas. The ASCU system monitors the operation of the replica no matter the speed of squeezing the trigger and is responsible for the full cycle of the piston’s operation, both in the semi-automatic and full automatic firing modes. The piston stops in the starting position after each shot.

The ASCU is equipped with the Low Drain Protection system which is specially designed to secure the lithium-polymer (LiPo) batteries from being damaged.

In case of any emergency, the ASCU stops the firing mode in the replica and, therefore, secures the inner elements from further damage.

The ASCU is easy to install in the replica which is equipped in the V.2 gearbox. Most of the models does not require the modification of the airsoft rifle’s original parts. Yet, in some cases, some minor changes may have to be introduced – thanks to this the installation process will be completed without any problems.

Velocity [FPS]:

It is the spped of bb, while its leaving the innerbarrel of replica. This speed is measured in FPS (Feet Per Second).

1 FPS = 0,3 m/s

1 J = 99 m/s

1 J = 326,7 FPS

Propulsion / Powered by:
Gearbox version:

Indications v2, v3, v6 does not mean the level of advance, but only shape of gearbox skeleton which was used and selected by the manufacturer depending on the capabilities of the body of the replica. For example, a models of the M4/M16 family, MP5, have a v2 gearbox, while the AK family have gearbox v3.

v2 Gearbox
Type of fire:
Single, auto
Lenght [mm]:

The length of the replca is measured between the two most distant points of each other. Different models have several of these values, because of its design allows to increase or decrease it length (eg.  folding stock or extended flash hider).

Inner barrel length [mm]:
Weight [g]:

This is a value that includes the weight of the replica, magazine and other accessories that are include in set without a battery, charger, cleaning rod, etc., etc.

Battery Capacity [mAh]:

Battery capacity determines the time, which it accumulated enough energy to work gearbox. The greater  capacity, then replica will shoot longer.

Magazine type:
Hi-Cap magazine
Magazine capacity [pcs]:

Hop-Up system is used for overclocking bb during the shot (putting it in rotation), through which, it extends its flight path. Acting laws of physics make that bb lift up, while the gravitational force take it down. Appropriate adjustment of Hop-Up, will compensate for these two factors, which result in long and straight flight for longer distance and be greater focus shot (to improve accuracy).

Yes, adjustable
Blow Back:

Blow back is a simulation system of the cocking lever - it imitates the work of it as the equivalent sharp. This system raises the realism and adds a lot more experience during shooting.

Made of:
Metal + plastic
Battery included:

NiCd rechargeable battery is characterized by high efficiency current-carrying capacity, but there are disruptive effect on memory. Should be unloaded and loaded in the full cycle, ie, it is recommended to fully discharge, and after unloading must charge the battery immediately without leaving it for a long time in a discharged state.
NiMH batteries have a higher self-discharge over time and shorten the life - on the other hand, they earn about 30% more capacity.
