M4 SA-C12 CORE HAL ETU HALF-TAN RIFLE SPECNA ARMS (SPE-01-041699)

The body, slide and battery compartment of the enlarged SF stock, foregrip and pistol grip are made of fiber-reinforced nylon polymer.
Other components, such as the barrel, black flash hider, extended cocking handle and tactical sling attachment group are made of metal (all screws, pins, bearing ejection port and bolt catch are made of steel).
The markings and serial number have been applied to the barrel.
The replica is mounted very well, the user will not feel any play between the lower and upper body.
The use of a lightweight polymer body has helped reduce its weight, making it perfect for dynamic gaming or prolonged milliseconds.
Additionally, the fiberglass reinforcement makes the body stronger than polymer and metal bodies.
The replica uses the esa™ quick-change spring system.
This allows the power of the replica to be adapted quickly and efficiently to the conditions expected on the playing field, without the need for access to a workshop or numerous special tools: it is simply necessary to unscrew the stock guide to gain access to replace the spring without having to extract or disassemble the gearbox.
The esa™ system allows, in a minimum time, to replace the main spring and therefore to adapt the discharge speed of the replica to the playing area, so as to guarantee an ideal compromise between the effectiveness of fire control and the safety of oneself and other players.
The replica has been fully adapted to operate on lipo and life type batteries. With a basic initial discharge velocity of ~380 fps guaranteed by the pre-installed main spring, the replica is perfectly suited for medium range operations.
Also included is an m90-type spring, which allows the muzzle velocity to be reduced to ~310 fps, making the replica perfectly suited for close-range or indoor operations.
The gearbox hides 8mm plain bearings and supported steel gears.
The system is secured by four anti-reversal ratchets.
The lightweight polycarbonate piston features a full steel rod for added strength. A type 2 cylinder and steel cutting lever are also used, and the strength of the components allows them to work with m140 springs.
The finely machined rotating hop-up chamber meshes perfectly with the high-quality 6.03mm precision barrel.
Using 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 ris rail and an adjustable stock.
Thanks to the extendable stock finished with a textured anti-slip plate, the length of the replica can be adjusted according to the shooter's size and preferences.
The standard flame arrester is mounted on a 14mm counterclockwise thread.
The kit includes an enlarged s-mag magazine with a capacity of up to 380 rounds.
The s-mag is a unique polymer magazine designed by specna arms.
What catches the eye is the distinctive texture composed of the specna arms logos.
The s-mag ensures trouble-free feeding, even with high rof.
