M4 SA-C12 CORE HAL ETU RIFLE BLACK SPECNA ARMS (SPE-01-041698)

The body, slide and battery compartment of the enlarged SF stock, the forend and the pistol grip are made of nylon fiber reinforced polymer plastic.
Other components, such as the barrel, flash suppressor, extended charging handle and tactical suspension assembly are made of metal (all screws, pins, case ejection port and dummy lock are made of steel).
The markings and serial number have been applied to the barrel.
The use of a lightweight plastic body has helped reduce its weight, making it perfect for dynamic games or extended practice.
Additionally, the fiberglass reinforcement makes the body more resistant than polymer and metal ones.
The replica uses the quick-change spring system, esa™.
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 extract or disassemble the gearbox.
The benefits of the esa™ system are difficult to quantify.
Considering the arrangements within the rooms themselves, this system guarantees the user considerable possibilities and great freedom.
The esa™ system allows you to change the spring and therefore adapt the speed of discharge of the replica to the playing area, so as to guarantee an ideal compromise between the effectiveness of fire control and the safety of yourself and other players.
The replica has been fully adapted to work with lipo and life type batteries.
With a basic initial fire rate of ~380 fps ensured by the pre-installed spring, the replica is perfectly suited for medium-range operations.
Also included is an m90 type spring that allows the muzzle velocity to be reduced to ~310 fps, making the replica perfectly suited for close-range or indoor operations.
The gearbox hides 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 bar for greater resistance.
Here too, a type 2 cylinder and a steel interrupter are used, the robustness of which allows working with m140 springs.
The finely crafted rotary hop-up chamber works 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 dorsal rail and an adjustable stock.
A classic carrying handle with sight has been mounted on the upper rail.
Thanks to an extendable buttstock, finished with a non-slip footboard, the length of the replica can be adjusted according to the shooter's build and preferences.
The standard flame muffler is mounted on a 14mm left-hand thread, which allows a sound suppressor to be fitted in its place.
The kit includes a hi-cap 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 characteristic texture composed of the specna arms logos.
The s-mag ensures trouble-free ball feeding, even at high rofs.
