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
depending on the capabilities of the body of the replica. For example,
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).

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.
The one I received had a missing screw in the bolt handle, causing it to flop freely.
However, beyond that minor detail, the gun works perfectly. It is easy to use, it is ergomonic and thanks to the bullpup design all the weight is at the back, which allows you to carry the gun for longer periods without tiring your arm.
If you are used to traditional gun layout, it can take a while to get used to the reloading, but once you get a hand of it is just as easy as with any other gun.
The rifle includes real Steyr AUG style quick dismantling, as well as quick spring change system. You can easily dismantle this gun, clean it up and put it back together without having to fiddle with screws at all.
The battery space should be noted. It is a the stock. This is relatively small space, so one should get a "candy bar" style battery to properly fit in.
The integrated picatinny rail on top serves both as a carry handle as well as a mount for optics. I would recommend to shop for a sight if you are planning on buying this gun, since the rifle comes with none of its own, one of the few true downsides.
Also, if your handle is working (or you fixed it with a small screw like I did), you can do HK (Steyr?) slap with this gun.
