Specna Arms ONE line replicas are made largely of a zinc and aluminum alloy, reinforced with steel elements in the most vulnerable points such as pins, screws, etc.
The stock and grip are made of polymer.
The replica's receiver and RIS handguard have been subjected to the anodizing process, which ensures a high degree of protection against corrosion.
The paint was applied using a powder coating process, after sandblasting the surface prior to application. This provides much higher abrasion resistance.

The replica's parts are very well aligned - in a way that until now could only be seen in replicas from high-end manufacturers, making it perfectly balanced.
This allows for almost ideal maneuverability of the replica and its weight is almost imperceptible when held in the hand.

The Kestrel V2 basic ETU module from Eshooter is an advanced ETU system featuring ease of use, durability and functionality.
The Kestrel™ V2 basic is trigger programmable, works with brush and brushless motors in high-speed and high-torque configurations, increases the reliability of the replica and protects internal parts in the event of overload due to motor damage or battery discharge.

Kestrel™ ETU Features:
- binary trigger. The replica fires when the trigger is pressed, and the next shot is fired when the trigger is released.
- Programmable 5-stage pre-cocking with piston position learning function. (The function requires several single shots after connecting the battery for calibration.)
- active brake. The replica performs a complete cycle with each click, so that unnecessary overloading of the gearbox is not created by executing only part of the cycle.
-locked rotor protection, a feature that protects the inside of the replica in the event of engine damage
- Battery discharge protection, protects against battery discharge. The motor vibrates, and the blue LED lights up five times to indicate low battery.
- Low/high voltage protection. The module detects the number of battery cells and adjusts operation to different cell counts and voltages from 6 to 17 V.
