DESIGN
This rifle features a 6-position adjustable stock, providing flexibility for different shooting situations. As a true replica of the original, this weapon features an ambidextrous fire selector, offering Safe and Semi-Auto modes, as well as bolt catch levers and magazine release buttons that are accessible from both sides.

ERGONOMIC CONSTRUCTION 
The EC203 features an extended 22mm RIS rail on top, along with a front handguard equipped with M-Lok System rails, allowing for easy attachment of accessories such as flashlights, bipods, and other attachments. Additionally, the handguard includes QD system mounts on both sides for sling attachment. Mechanical sights are mounted on the top RIS rail which can be replaced if wanted. 

ACCURATE PRECISION
Precision is ensured by a 6.04mm diameter barrel and reinforced rotary hop-up chamber made of polymer. For ease of hop-up system adjustment, the rifle is equipped with a functioning bolt catch.

INTEGRATED MOSFET
The EC203 airsoft replica is built with precision mechanics and high quality parts. It features a dedicated long-type V2 gearbox with a quick spring change system, all compatible with TM standards.
The gearbox includes steel gears mounted on 8mm ball bearings, while compression is managed by a long-type 0 cylinder and the piston is designed with metal teeth for enhanced durability.
The protection of wires and various programming modes is ensured by the Eshooter ETU Basic system. As a faithful replica, this model is set by default to fire Single Fire SEMI MODE. To further customise this, demanding players can switch the modes to (BURST, AUTO) in the AUTO position and (BINARY) in the SEMI position. 
The mosfet regulates the current intensity and allows:

Pre-cocking Adjustment: Different 5 pre-cocking levels to programming. The KESTREL Basic have learning function which can automatically determine the position of pre-cocking stop based on different speeds and loads. It is normal for a single shot to fire a few more rounds after replug or unplug the battery.
Support Brushless Motor: Support brushless and high-speed/high-torque motors.
Long Lasting Shooting: Perfectly working even over 50k shots.
Active Braking: Adaptive function to avoid gear instability, ensure piston stops in front position, increase gearbox and inside parts’ service life.
