Specna Arms to meet the expectations of customers presents the CORE™line - a unique series of replicas, which introduces a new quality on the market. Attractive price in combination with an innovative spring replacement system and high quality materials makes this series for both beginners and seasoned airsoft players. The body, the slide and the enlarged SF-type buttstock, which accommodates the battery, as well as the pistol grip, are made of polymer polymer reinforced with nylon fibre. Other components, such as the barrel, RIS front, flame suppressor, enlarged reloading handle and tactical sling assembly are made of metal (all screws, pins, shell ejection window and dummy lock are made of steel). Markings and serial number have been applied on the body.

The replica is very well-fitted, the user will not experience any play between the lower and upper parts of the body. The use of lightweight polymer body allowed to reduce the weight, which makes it perfect for dynamic games or prolonged milslims.

Furthermore, the fibreglass reinforcement also makes the body stronger than polymer and metal bodies. The replica uses the quick spring change system, ESA™. This allows quick and efficient adjustment of the replica's power to the conditions expected on the field of play without the need for access to a workshop or a number of specialised tools - simply unscrew the butt guide to reveal access to exchange the spring without having to pull out or disassemble the gearbox.

The advantages of the ESA™ system are difficult to overstate. In view of the arrangements within the environments themselves, this system guarantees the user considerable possibilities and a great deal of freedom. The ESA™ system makes it possible, with a minimum of time, to change the mainspring and, consequently, to adjust the replica's discharge velocity to the area of play so as to guarantee an ideal compromise between the effectiveness of the firearm and the safety of oneself and other players.

The replica has been fully adapted to work with LiPo and LiFe type batteries. With a base initial discharge velocity of ~380 FPS guaranteed by the pre-installed mainspring, the replica is perfectly suited for medium range operations. An M90-type spring is also included, allowing the initial velocity to be reduced to ~310 FPS, making the replica perfectly suited for short-range or indoor operations.

The gearbox conceals 8-mm slide bearings and the supported steel gears. The system is secured by four anti-reverse pawls. The lightweight polycarbonate piston is fitted with a full steel bar for added strength. It also uses a Type 0 cylinder and steel cut-off lever, as well as a precision rotary hop-up chamber. The strength of the parts allows them to work with M140 springs. The finely crafted Rotary Hop-Up chamber works perfectly with the high quality 6.03mm precision barrel.

The use of a precision barrel positively affects the range and accuracy of the replica. It is important to remember to use high quality 6mm ammunition. The replica is equipped with a 22mm dorsal RIS rail, a set of front RIS rails and an adjustable buttstock. A folding sight has been fitted on the top RIS rail, which does not interfere with optoelectronic sighting devices. Thanks to the extendable buttstock finished with a non-slip textured foot, it is possible to adjust the length of the replica to the build and the shooter's preferences. The standard flame suppressor is mounted on a 14-mm left-hand thread, which makes it possible to attach a sound suppressor in its place.
