M4 SMR SA-A37 ONE KESTREL ETU GRAY SPECNA ARMS RIFLE (SPE-01-043423)

The replica uses a quick spring change system, the so-called enter & convert.
This allows for quick and efficient adjustment of the replica's power to the expected conditions on the playing field, without the need for access to a workshop or specialized tools.
After removing the gearbox from the replica body, the process of replacing the spring literally takes seconds.
In light of the prevailing trend in Europe towards legal limits on replica download speed and existing regulations in the environments themselves, this system provides the user with extensive options and freedom.
The enter & convert system allows you to replace the main spring in minimal time and therefore adapt the exit speed of the replica to the playing area, ensuring an ideal compromise between the effectiveness of the weapon and the safety of you and other players.
The replica has been fully adapted to work with lipo and life type batteries.
The reducer, reinforced at the head height, hides a steel spring guide which is part of the enter & convert system and is mounted on 8 mm ball bearings and washers, 16:1 ratio steel gears made with numerically controlled machines.
The system is secured with four anti-reversal ratchets.
The lightweight polycarbonate piston features a steel tooth for increased strength.
It also uses a Type 2 cylinder and steel cutting lever, as well as a polymer lop-up chamber.
The replica is also equipped with a Specna Arms Dark Matter brushless motor (27000 rpm).

The eshooter Kestrel v2 Basic ETU Module is an advanced ETU system that stands out for its ease of use, robustness and functionality.
The Kestrel v2 Basic is programmable with triggers, works with brushless and brushless motors in high-speed and high-torque configurations, increases the reliability of the replica, and protects internal components in the event of overloads due to motor or battery damage.

Kestrel Basic System Features:
binary trigger. The replica fires when the trigger is pulled, and another shot will be fired when the trigger is released.
5-stage programmable pre-cocking with piston position learning function (this function requires several single shots after connecting the battery for calibration).
active brake.
The replica performs a full cycle on each shot, so as to avoid unnecessary overloads in the gearbox due to the execution of part of the cycle.
Locked Rotor Protection, the function protects the inside of the replica in case of engine damage.
Battery discharge protection. Battery discharge protection.
The motor vibrates, the blue LED lights up five times to indicate low battery.
Low/High Voltage Protection. The module detects the number of cells in the battery and adjusts operation to different cell numbers and voltages from 6v to 17v.
