Specna Arms SA-A37 ONE™ BLDC™ Kestrel™ ETU Chaos Bronze airsoft Carbine

Specna Arms SA-A37 ONE™ Kestrel™ ETU airsoft Carbine

The brushless BLDC™ (Brush Less Direct Current) motor is a direct current motor in which the classic brushes responsible for current transmission have been eliminated.

• no sparking
• longer service life (no wearing parts)
• stable performance even at high speeds
• high energy efficiency
• quiet operation
• lower heat generation
• immediate response to the trigger
• high torque right from the start
• allows the use of hard springs without loss of performance or rpm

Eshooter's Kestrel™ V2 Basic ETU module is an advanced ETU system characterised by 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 overload due to motor damage or battery drain.

Kestrel™ Basicchip features:

-Binary trigger. the replica will fire when the trigger is pressed and the next shot will be fired when the trigger is released.

-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 overload is created in the GB due to performing part of the cycle.
-Locked Rotor Protection, a function that protects the inside of the replica in the event of motor damage
-Battery Drain Protection, protects against battery drain. The motor vibrates, the blue LED lights up five times to indicate battery discharge
-Low/ High Voltage Protection. the module detects the number of battery cells and adjusts operation to different cell counts and voltages from 6V to 17V.

Specna Arms SA-A37 ONE™ Kestrel™ ETU airsoft carbine

The replica of the SA-A37 carbine by Specna Arms is made predominantly from a uniform zinc and aluminium alloy, with the use of steel elements in the most critical points of the replica (thus, all screws, pins and the tactical sling mount are steel). The body of the replica and the RIS rail assembly were subjected to an anodising process, which guarantees a high level of protection of the replica against corrosion . The replica itself was painted using 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 is very well-fitted - in a way that could previously only be seen almost exclusively in the G&P or Classic Army class of manufacturers - and perfectly balanced. This ensures the ideal manoeuvrability of the replica, while its weight is also almost imperceptible once the replica is placed against the shoulder.

The replica uses a quick-change spring system, the so-called Enter & Convert™. This allows quick and efficient adjustment of the replica's power to the conditions expected on the battlefield without the need for access to a workshop or a range of specialised tools - after removing the gearbox from the body of the replica, the spring change process itself takes literally seconds.

The advantages of the Enter & Convert™ system are difficult to overestimate. In light of the prevailing tendency throughout Europe to apply legal limits to the firing speed of the replica and the arrangements existing within the environments themselves, this system guarantees the user considerable possibilities and a great deal of freedom. The Enter & Convert™ system makes it possible , with a minimum of time, to change themainspring and thus adjust the replica's discharge velocity to the playing area so as to guarantee an ideal compromise between the effectiveness of the firearm and the safety of oneself and other players.

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

The gearbox, reinforced at the height of the cylinder head, houses a steel spring guide that is part of the Enter & Convert™ system, as well as 16:1 steel gearsmounted on 8mm ball bearings and washers made with CNC equipment. The system is secured by four anti-reverse pawls. The lightweight polycarbonate piston is fitted with a steel tooth to increase its strength. A Type 2 cylinder and steel cut-off lever are also used here , as well as a polymer hop-up chamber.
The replica also features a Specna Arms Dark Matter™ brushless motor (27000RPM).

The Upgraded version has a number of new reinforced parts such as:

- a set of reinforced steel gears
- steel spring guide
- lightweight polymer piston
- sealed aluminium piston head
- metal cylinder head
- sealed metal nozzle

The replica is equipped with a 22mm dorsal RIS rail, a set of front MLOK rails and an adjustable buttstock. On the upper RIS rail, flip-up sighting devices have been fitted, but they 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 game, the replica has also been equipped with a functioning breech release.

The replica also comes with a hi-cap type magazine, holding 300 rounds.
