GK74N carbine replica
The GK74N carbine replica is made of steel and wood. Only the pistol grip was made of plastic. The stock's length fixed and the total length of the replica is 970mm.
The firing mode selection lever is located on the right side of the replica and is marked with graphic markings of the firing mode. The replica is equipped with the PBB system which perfectly imitates the operation of the original equivalent. It sets the bolt carrier dummy in motion and gives a perceptible "kick" effect felt on the shooter's shoulder.
After pulling the cocking handle, the dust cover opens and the bolt carrier's dummy moves backwards to the rear position. This allows to adjust the hop-up system.
The replica was made in black color. It is perfect to be used on middle and short distances.
An extraordinary Blow-Back system 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.
The G&G replica’s that are equipped with the Pneumatic Blow-Back system have got a reinforced and modified V.3 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.
This model also uses an innovational powering system. Considering the problems
with fitting the LiPo batteries under the bolt cover, the manufacturer
introduced another solution – the LiPo battery was built in the front grip. The
battery is a LiPo 11.1V 22C 1100mah battery. The set also includes a spare grip
with a battery and a charger equipped with an balancer.
The set includes a battery and a charger.
The set includes:
- the carbine
replica,
- a magazine,
- a LiPo battery in the grip – 2 pieces,
- a charger,
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.
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.
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
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.
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).
