Perfectly balancing performance and adaptability, the Specna Arms C-Series CORE ETU Airsoft AEG Rifle is engineered to excel in both casual skirmishes and rigorous mil-sim operations. Its lightweight nylon-reinforced polymer frame combines durability with comfort, making it ideal for extended gameplay without sacrificing portability. Designed for versatility on any field, this carbine features Specna’s proprietary ESA2 Quick Spring Change System—a game-changer that lets users swap main springs in seconds without tools or disassembly. Whether you’re competing indoors or outdoors, toggle between the factory-installed 380 FPS spring or switch to the included M90 spring for a reduced 310 FPS velocity to meet safety regulations effortlessly.

At its core lies a reinforced Version 2 gearbox fitted with steel gears and slide bearings for unmatched reliability under heavy use. The pre-installed HAL MOSFET ensures smooth motor operation while protecting against electrical stress during rapid fire sessions. Precision comes standard thanks to its tight-bore 6.03mm barrel paired with Specna’s Helium flat hop bucking in a rotary hop-up system—delivering consistent accuracy across distances up to medium range scenarios.

Customize your setup effortlessly using its full-length metal M-LOK handguard compatible with lights, lasers, grips, and optics mounts. The ergonomic adjustable crane stock offers six length configurations while doubling as a secure battery compartment inside its design—a unique feature simplifying power management during gameplay. Beginners appreciate its smooth flat trigger pull and intuitive controls; veterans value its upgradeable gearbox compatibility with high-tension springs like M140 variants for enhanced performance tuning possibilities.

Included out of the box are a high-capacity 380-round S-Mag magazine, flip-up iron sights for backup targeting needs, three rail segments for accessory integration, plus an extra M90 spring bundle ready to optimize your velocity instantly based on field requirements or personal preference.
