Specna Arms meeting customer expectations presents the line CORE™ -an exceptional series of replicas that introduces a new quality in the market. It caters to both novice and experienced airsoft players.

The Specna Arms J-Series™ CORE™ carbines are made primarily from durable nylon fiber-reinforced polymer, making the replica very light and comfortable. The model in question is made of a 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, barrel base with the stock, bed holder, barrel, and musket were made from zinc alloy and aluminum. The lock chamber cover, fuse wing, trigger holster, buttstock, and rear suspension eyelet are made of steel.

Specna Arms J-Series™ CORE™ characterized 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.
