BI-3381M carbine replica
A replica made out of a zinc-aluminium alloy and high quality, durable plastic. The elements such as the replica's receiver, outer barrel, stockpipe, all RIS rails and most minor elements have been made out of metal. What's worth noting, the hop-up chamber was also made of metal. Other outer elements, such as the SF-type stock and the pistol grip, ahve been made out of plastic.
The replica is equipped with a regulated hop-up system which allows for much more precise shooting. It's easily accessed by pulling away the t-lever, thus opening up the dummy chamber and revealing the regulation mechanism. The replica's v2 gearbox was made out of metal and has been equipped with a durable ABS piston and metal torques set on 7 mm bearings.
The set includes:
- the replica
- a magazine
- a battery
- a charger
- a tactical foregrip
- a three-point sling
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:|
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).
780 / 860
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.
|Battery Voltage [V]:|
|Battery Capacity [mAh]:|
Battery capacity determines the time, which it accumulated enough energy to work gearbox. The greater capacity, then replica will shoot longer.
|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.
The only cons I could find is that the stock has a little wobble and the magazine should be put in carefully, it is a little too small for the magazine well.
Mine came with a M100 spring pre-installed by gunfire, it shoot 336fps steady.
