Specna Arms SA-C01 CORE™ M4 Carbine Airsoft Rifle – Black
The Specna Arms SA-C01 CORE™ M4 Carbine is a lightweight, well-balanced airsoft rifle designed for speed, versatility, and ease of use. Built with new players and experienced skirmishers in mind, this replica features a durable nylon-reinforced polymer receiver, stock slide, and pistol grip – offering great resilience without the extra weight of a full-metal build. Key components such as the outer barrel, charging handle, and sling swivels are metal, while steel parts include the shell ejection window, screws, and mock bolt carrier. Everything fits together tightly, giving the rifle a solid and reliable feel straight out of the box.
One of the standout features is the ESA™ Quick Spring Change System, allowing users to change the spring without accessing the gearbox. This makes it easy to drop the muzzle velocity from 380 FPS (stock spring) to 310 FPS using the included M90 spring – perfect for indoor fields and close-quarter skirmishes. Internally, it features a metal gearbox with 8mm slide bearings, steel gears, a polycarbonate piston with steel teeth, and a tight 6.03mm precision inner barrel paired with a rotary Hop-Up. The result is consistent range and accuracy. This rifle is also compatible with LiPo and LiFe batteries, but a charger is not included.
