JG204 sub-machinegun replica 

A very well made and fitted replica of the PDW sub-machinegun. The replica’s body, the outer barrel, the iron aiming sights and the flash-hider are made of metal, while as the stock, the pistol grip and the front grip are made of nylon. The flash-hider and the stock can be easily detached in order to gain an even more compact replica. The stock itself can be folded to the side in order to facilitate the transport and storage.

The small dimensions, the proper balancing and the overall compactness make the JG201 a perfect replica for close-range skirmishes and for the CQB type games. The replica’s features are even greater thanks to the ambidextrous firing mode selection lever which allows for a comfortable and trouble-free change of the firing mode with both, the left and the right hand. What is important, the iron aiming sights are fully adjustable.

The replica is powered by a V.3 gearbox which is equipped with a set of steel thread-wheels which are placed on 7mm ball bearings. A metal ball bearing spring guide is also used and it significantly facilitates the operation of the mechanism. The gearbox is also equipped with an aluminum bushing on the piston. The replica is equipped with an increased torque motor.

The RIS rail set which is applied in the replica allows to attach different accessories to the replica - tactical grips, laser target markers, flashlights and red dot scopes. This significantly increases the value of the replica by developing its possibilities of adaptation to different conditions of the skirmishes.


The set includes:

- the replica,
- a battery,
- a charger,
- a magazine

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

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.

Battery Capacity [mAh]:

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

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.

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.

Very well made external. The rails and upper are all metal. The gun came over-greased and over-shimmed. It was shimmed out of the box but the gears were so tight, the original battery (which was kinda weak, about 5c) couldnt even crank the box. And the sticky grease made the trigger lock up on single shot all the time. It took me 4 hours to dissasemble, reshim and regrease everything. The internal is surprisingly good too. Sector gear came with a delayer. Piston is air tight. The barrel is so short, barely longer than a G17 pistol but the gun can hit torso targets at 35m easily. You get a excellent little package if you willing to spend some effort on the internal.

Excellent externals, and a decent rate of fire. The range was pretty good. The pins for the stock are made of a poor material, and one broke.
