The ASG SA-A01 ONE™ Kestrel™ ETU Black

The Kestrel V2 Basic ETU by Eshooter is an advanced ETU system featuring ease of use, durability 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 overload due to motor damage or battery drain.

Functions of the Kestrel Basic system:

-Pre-cocking programmable in 5 stages with piston position learning function. 
(function requires a few single shots after connecting the battery for calibration)
-Active Break. The replica performs a full cycle with each shot, so that no unnecessary overloads are created in the GB due to performing part of the cycle.
-Locked Rotor Protection, function protects the inside of the replica in case of damage to the motor
-Battery Drain Protection. Protection against battery discharge. The motor vibrates, the blue LED illuminates five times to indicate battery drain
-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 SA-A01 carbine replica by Specna Arms 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 mount are steel). The SF type stock, which houses the battery, as well as the pistol grip, are made of polymer plastic. The body of the replica and the RIS rail assembly have been subjected to the anodising 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 a much higher than usual abrasion resistance of the applied paint.

The replica has been very well-fitted - in a way that could previously be seen almost exclusively in manufacturers of the G&P or Classic Army class - and perfectly balanced. This ensures almost ideal manoeuvrability of the replica, while its weight is, in addition, when the replica is placed against the shoulder, almost imperceptible. 

The replica uses the quick 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 battlefield without the need to have access to a workshop or a number of specialised 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 throughout Europe towards legal restrictions on the firing speed of the replica 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 makes it possible with a minimum of time to replace the mainspring and thus adapt the replica's exit velocity to the playing area so as to guarantee an ideal compromise between the effectiveness of the firearm and the safety of yourself and other players.

The replica has been fully adapted to work with batteries of the type LiPo and LiFe. With a base initial discharge velocity of the order ~410 FPS guaranteed by the pre-installed mainspring, the replica is perfectly suited for medium range operations. A M90-type spring is also included, which allows the initial velocity to be reduced to ~310 FPS making the replica perfectly suited for short range or indoor operations.

The gearbox, reinforced at the height of the cylinder head, conceals a steel spring guide that is part of the Enter & Convert™ system and mounted on 8mm ball bearings and washers steel gears. The system is secured with four anti-reverse pawls. It also uses cylinder type 2 and steel cut-off lever. The replica is factory-fitted with an accurate, rotating polymer Hop-Up chamber which allows for very precise and stable adjustment of the BB overclocking system.

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 aluminium piston head
- a sealed metal cylinder head
- a sealed metal nozzle

The rifle is fitted with a 22mm dorsal RIS rail, a set of front RIS rails and an adjustable buttstock. Metal flip-up sights have been fitted on the upper RIS rail, but these can be freely replaced by any optoelectronic sighting device. Thanks to the sliding buttstock finished with an anti-slip textured footplate, it is possible to adjust the length of the replica to the shooter's build and preferences. The standard 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 functional breech release.

The replica also comes with a steel hi-cap magazine that holds 300 rounds.
