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.

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.

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

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.

Good externals. middle ROF - shoots 80 m/s with .28 BB's. Internals are not super. NOT ball bearing bushings, steel sliding bushings. NOT high torque motor. You will need to change nozzle, piston head and piston for acceptable performance.
