SPECNA ARMS M4A1 SA-C04 CORE HAL ETU RIFLE BLACK (SPE-01-041686)

Specna arms, to meet customer expectations, presents the core™ line
a unique series of replicas, which introduces a new quality to the market. The attractive price in combination with an innovative spring replacement system and high-quality materials makes this series suitable for both beginners and experienced airsoft players.
The body, slide and the enlarged SF-type stock, which houses the battery, as well as the pistol grip, are made of nylon fiber reinforced polymer plastic. Other components, such as the barrel, the forend, the flash suppressor, the enlarged charging handle and the tactical suspension group are made of metal (all screws, pins, the ejection port of the case and the dummy lock are made of steel). The body is marked with the serial number and markings.
The use of a lightweight plastic body has helped reduce its weight, making it perfect for dynamic play or extended practice. Additionally, the fiberglass reinforcement makes the body more durable than polymer and metal ones.
The replica uses the esa™ quick-change spring system. This system allows you to quickly and efficiently adjust the power of the replica to the conditions expected on the playing field, without having to access a workshop or a set of specialized tools: simply unscrew the stock guide to gain access to replace the spring without having to remove or disassemble the gearbox.
The advantages of the esa™ system are difficult to quantify. Considering the layouts within the environments themselves, this system guarantees the user considerable possibilities and great freedom. The esa™ system allows you to change the spring and, consequently, to adapt the speed of discharge of the replica to the playing area, so as to guarantee an ideal compromise between the effectiveness of the weapon and the safety of yourself and other players.
The replica has been fully adapted to operate with lipo and life type batteries. With a basic initial discharge rate of ~380 fps guaranteed by the pre-installed spring, the replica is perfectly suited for medium range operations. An m90 type spring is also included that allows the initial velocity to be reduced to ~310 fps, making the replica perfectly suited for short range or indoor operations.
The gearbox houses the 8mm slide bearings and supported steel gears. The system is secured by four anti-return pawls. The lightweight polycarbonate piston is equipped with a steel rod for added strength. It also uses a type 0 cylinder and steel stop, as well as a precision rotating hop-up chamber. The robustness of the components allows it to work with m140 springs.
The finely crafted rotary loading chamber works perfectly with the high-quality 6.03 mm 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 6 mm ammunition.
The replica is equipped with a 22 mm dorsal rail, a set of front rails and an adjustable stock. A folding front sight is mounted on the upper rail, which does not interfere with optoelectronic sights. Thanks to the extendable stock, finished with an anti-slip foot, it is possible to adjust the length of the replica to the shooter's build and preferences. The standard flash suppressor is mounted on a 14 mm left-hand thread, which allows for mounting a sound suppressor instead.
