6669 machine gun replica
This machine gun replica is almost entirely made of high-quality metal and, to a lesser extent, of a polymer.
The upper and lower receiver of the replica, barrel with quick release system and RIS / Keymod rail were made of metal. The replica has numerous attachment points for QD slings.
For manufacturing pistol grip and adjustable stock, producer used durable polymer. The stock has a compartment for a battery and an electric magazine with the capacity of up to 2500 BBs.
The replica has fixed, adjustable sights and RIS / Keymod rails that allow mounting various types of tactical accessories.
The heart of this replica is standard, modification-ready V2 Gearbox.
The set includes:
- replica
- magazine
- dummy bullet
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).
