GR4 100Y BB carbine replica
The GR4 100Y BB carbine replica made by the G&G company is made within the Combat Machine project which aim was to deliver a high class replica in the price that you could call economical. The Combat Machine replicas characterized themselves with the highest quality of make, high operating culture and the high quality of the materials used – what is very characteristic for the G&G company. The main factor allowing to lower the price is the use of the body and the front grip that were made of high quality plastic instead of metal. It is also significant that the body itself is made of plastic that was reinforced with fiberglass – just like the front grip, the stock and almost every plastic element. The iron aiming sights, the magazine, the stock and the cocking handle were made of metal. The shape of the piston grip is almost identical to the real firearm’s pistol grip.
The front grip is equipped with RIS rails and the top rail overlaps with the replica’s body. Thanks to this fact, the user gains a rail that is 340mm long. There are iron aiming sights located on the top rail – the front and the classical rear sight.
The replica was made in black color. Thanks to the compact size the replica is perfect for short and middle distances and thanks to the use of a M100 main spring the operator gains the muzzle velocity of about 310-320 FPS. The use of the top RIS rail allows to attach any optical aiming device and the collapsible stock allows to adapt the replica to fight in close distances.
An extraordinary Blow-Back system, known from the Top Tech replica ( the more “professional” and what follows it – the more expensive G&G line ), provides additional realism for the user of the replica and ensures additional experiences for the user himself.
The Pneumatic Blow-Back system operates on the principal of taking a part of the compressed air from the gearbox to a special cylinder that is located above the gearbox’s casing. The small piston that is located in the Pneumatic Blow-Back system moves a thin plate that is attached to it. The plate imitates the bolt carrier.
ATTENTION: The manufacturer does not recommend using batteries stronger than 8,4V due to the fact of the possibility of damaging the aforementioned plate.
The G&G replica’s that are equipped with the Pneumatic Blow-Back system have got a reinforced and modified V.2 gearbox. The modification that was made was the adaptation of the gearbox to the Pneumatic Blow-Back system and adding the “active main spring release” button in the form of the actuator. It is impossible to use any other gearbox casing with the Pneumatic Blow-Back system and the main spring release.
The set includes:
- the replica,
- a magazine

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:|
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.
|Type of fire:|
|Diameter of bearings in GB [mm]:|
Metal + plastic
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]:|
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.
|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).
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.
