The Specna Arms SA-A37 ONE Kestrel ETU airsoft rifle
The Kestrel module V2 Basic ETU by Eshooter is an advanced ETU system featuring ease of use, robustness, and functionality. The Kestrel V2 Basic is programmable with trigger pulls, works with both brush and brushless motors in High Speed and High Torque configurations, and increases the reliability of the replica and protects internal parts in the event of overloads due to motor damage or battery drain.
Functions of the Kestrel system Basic:
- Binary trigger. The Replica will fire when the trigger is pressed, and another shot will be fired when the trigger is released.
- Pre-cocking programmable in 5 stages with piston position learning function. (feature requires several single shots after battery connection for calibration)
- Active Break. The replica performs a full cycle with each shot, so that no unnecessary overload is created in the GB due to performing part of the cycle.
- Locked Rotor Protection. The feature protects the inside of the replica in case of damage to the motor
- Battery Drain Protection. Battery Drain Protection. The motor vibrates, the blue LED illuminates five times to indicate battery discharge
- Low/ High Voltage Protection. The module detects the number of battery cells and adjusts operation to different numbers of cells and voltages from 6V to 17V.
The Specna Arms SA-A37 ONE Kestrel ETU airsoft rifle
Replica of the SA-A37 carbine of the Specna Arms brand has been made predominantly from a uniform zinc-aluminium alloy, with the use of steel elements in the most critical points of the replica (so all screws, pins, and the tactical sling handle are steel). The stock and pistol grip are made of polymer polymer. The body of the replica and the RIS rail assembly have been subjected to the anodizing process, which guarantees a high degree of protection of the replica against corrosion. The painting of the replica itself was done by a powder coating process, after the surface had been sandblasted. This ensures that the applied paint is much more abrasion-resistant than usual.
The replica uses a fast spring change system, the so-called Enter & Convert. This allows for 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 specialized tools - after removing the gearbox from the body of the replica, the spring replacement process itself takes literally seconds.
The advantages of the Enter & Convert system are difficult to overestimate. In light of the prevailing trend across Europe towards legal limits on replica discharge velocity and the arrangements that exist within the environments themselves, this system guarantees the user considerable options and a great deal of freedom. The Enter & Convert system allows with a minimum of time to replace the mainspring and thus to adapt the replica's exit velocity to the area of play so as to guarantee the ideal compromise between the effectiveness of the firing and the safety of yourself and other players.
The replica has been fully adapted to work with battery types LiPo and LiFe. With a base initial discharge velocity of around ~410 FPS guaranteed by the factory-installed mainspring, the replica is ideal for medium-range operations. Also included is a M90-type spring which reduces the initial velocity to ~310 FPS making the replica perfectly suited for short-range or indoor operations.
The gearbox, reinforced at cylinder head height, conceals a steel spring guide that is part of the Enter & Convert system and mounted on 8mm ball bearings and washers steel 16_1 gears made using CNC equipment. The system is secured with four anti-reverse pawls. The lightweight polycarbonate piston is fitted with a steel tooth to increase its strength. It also uses cylinder type 2 and steel cut-off lever as well as polymer hop-up chamber. The replica also features a Specna Arms Dark Matter brushless motor (27000RPM).
Upgraded version has a number of new reinforced parts such as:
- a set of reinforced steel gears
- a steel spring guide
- a lightweight polymer piston
- a sealed aluminum piston head
- a sealed metal cylinder head
- a sealed metal nozzle
The Upgraded version is fitted with a 22mm dorsal RIS rail, a set of front MLOK rails, and an adjustable buttstock. A flip-up sighting device has been fitted on the upper RIS rail, but can be freely replaced by any optoelectronic sighting device. Thanks to an extendable buttstock finished with a foot with an anti-slip texture, it is possible to adjust the length of the replica to the shooter's build and preferences. The flame suppressor is mounted on a 14-mm left-hand thread, which makes it possible to attach a sound suppressor in its place.
To increase the realism of the gameplay, the replica is also equipped with a functioning breech release.
The replica also comes with a hi-cap magazine that holds 300 rounds.
