CORE⢠Line Overview
The CORE⢠series offers quality and value, making it suitable for both beginners and seasoned airsoft players. Featuring an innovative spring replacement system and high-quality materials, this line sets a new standard.
Build and Durability
The SA-C03 CORE⢠is designed for robustness and lightweight use. The body, slide, and SF-type buttstock are made of polymer reinforced with nylon fiber, while the barrel, RIS front, flame suppressor, and tactical sling mounts are crafted from metal. All screws, pins, and dummy lock are steel. Serial numbers and markings add an authentic touch to the body.
Quick Spring Change System - ESAā¢
The ESA⢠quick spring change system allows you to adjust the replica's power without specialized tools. Simply unscrew the butt guide to access and change the spring, adapting the discharge speed to the game area for maximum performance and safety.
Power and Battery Compatibility
This replica is optimized for LiPo and LiFe batteries, offering a standard velocity of ~380 FPS with the pre-installed spring. The included M90-type spring reduces this to ~310 FPS, perfect for indoor and short-range play.
Gearbox and Internal Mechanisms
The V2 gearbox houses 8-mm slide bearings and steel gears, secured by four anti-reverse pawls. A polycarbonate piston with a steel bar, Type 0 cylinder, and steel cut-off lever ensure durability, while the rotary hop-up chamber and 6.03mm precision barrel deliver enhanced range and accuracy.
