The model in question is made of polymer flask, pistol grip, body extrusion including flask holder, bed with gas tube cap, gas tube and base of the musket.
The most critical parts, such as the barrel holder, dummy slide, the barrel base with the stock, the bed holder, the barrel and the musket were made from zinc alloy and aluminium. The lock chamber cover, fuse wing, trigger holster, buttstock and rear suspension eyelet are made of steel.
Specna Arms J-Series™ CORE™ characterised by very good fit, low weight and ergonomics. In addition, the replica has been equipped with the quick spring replacement system ESA2™. The system allows the power of the replica to be adjusted without disassembling the replica. To replace the spring, simply remove the lock chamber cover, fold the buttstock and unscrew the screw holding the spring guide.
Features of the replica:
- body made of plastic
- low weight
- very good fit
- metal hop-up chamber
- precision barrel internal 6.03mm diameter
- fast spring change system ESA2™
- included additional mainspring M90
- exit device on 24mm CW / 14mm CCW thread
- side mounting rail type "dovetail"
- realistic VFC system construction, based on pins, levers and pins
- plenty of space for a stick battery under the breech chamber cover (LiPo ready)
- full flask, folds to the side of the body
- insert magwell walk easy magazine change
- originally designed magazines mid-cap S-MAG
Most types of magazines made by Cyma, JG, E&L, Bolt will fit the replica seamlessly, fitting magazines from other brands may require minor modifications.
The replica has been fully adapted to work with batteries of the type LiPo and LiFe. Thanks to the base initial discharge velocity of the order ~380 FPS guaranteed by the factory-installed mainspring, the replica is perfect for medium range operations. A M90-type spring is also included, which allows the initial velocity to be reduced to ~310 FPS thus making the replica perfectly suited for short-range or indoor operations.
The gearbox conceals 8-millimetre slide bearings and the supported steel gears mounted on them. The system is secured by four anti-reverse pawls. The lightweight, polycarbonate plastic piston is provided with a full steel bar to increase its strength. It also uses a cylinder type 0 and steel interrupter. The strength of the parts allows it to work with M140 springs.

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).
