SA-J72 CORE™ Carbine Replica
Specna Arms, in order to meet the expectations of its customers, presents the CORE ™ line - a unique series of replicas that introduces a new quality on the airspeed replica market. An affordable price combined with an innovative quick spring change system, great performance straight out of the box and high-quality components makes this series an excellent choice for both beginners and experienced airsoft players alike.
Specna Arms J-Series ™ CORE ™ carbine replicas are made primarily out of durable polymer reinforced with nylon fiber, making the replica lightweight and comfortable to use. Pistol grip, stock, receiver, handguard with the gas tube cover, gas tube and the front sight post are made of polymer.
The most crucial elements, such as the barrel mount, dummy bolt carrier, rear sight, barrel and front sight are made out of zinc and aluminum alloy. The dust cover, safety, trigger guard and the stock are made out of steel.
Specna Arms J-Series ™ CORE ™ features a very good fit of the parts, ergonomics and low weight. In addition, the replica comes equipped with the ESA2™ quick spring change system. The system allows you to adjust the power of the replica without the necessity to disassemble the replica. To replace the spring, you just need to remove the dust cover, fold the stock and unscrew the screw holding the spring guide.
Features of the replica:
- receiver is made out of plastic
- low weight
- well-fitted
- metal hop-up chamber
- 6.03 mm diameter precision barrel
- ESA2 ™ quick spring change system
- additional M90 main spring included
- muzzle device on a 24mm CW / 14mm CCW thread
- "dovetail" type side mounting rail
- realistic design in the VFC system, based on pins, levers and pins
- plenty of room for a stick battery under the dust cover (LiPo ready)
- full stock, folded to the side
- magwell spacer for easy magazine reloading
- original S-MAG hi-cap magazines
The replica is compatible with most types of Cyma, JG, E&L and Bolt magazines, the matching of magazines from other brands may require some minor modifications.
The replica has been fully adapted to work with LiPo and LiFe batteries. Thanks to the basic muzzle velocity of ~ 380 FPS guaranteed by the factory-installed main spring, the replica is perfect for middle-range operations. The set also includes an M90 spring, which allows you to reduce the initial muzzle velocity to ~ 310 FPS, making it the replica perfectly adapted to operate at short distances or inside buildings.
The gearbox has 8 mm slide bearings and steel gears fitted on them. The system is secured by means of four anti-reversal latches. A light, made out of polycarbonate plastic piston is fitted with a full steel tappet plate increasing its durability. A type 0 cylinder and a steel circuit-breaker are also used here. The durability of the components allows for using M140 springs.
The set does not include a battery or a charger.
The set includes:
- replica
- magazine
- additional M90 main spring
- user manual

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).
