Specna Arms RRA SA-C05 CORE™ X-ASR™ Carbine Replica – Black

Official Rock River Arms Licensed Replica

The SA-C05 CORE™ is a next-generation airsoft carbine from Specna Arms, featuring fully licensed Rock River Arms® trademarks. Combining high-quality materials with reliable internals, it’s engineered for both beginners and experienced airsoft players. This model offers excellent performance, reduced weight, and a cutting-edge spring change system—all at an accessible price point.

Durable Lightweight Construction

External elements such as the receiver, SF-style stock, stock slide, and pistol grip are made of nylon-reinforced polymer—lightweight, impact-resistant, and reinforced with fiberglass for enhanced durability. Key components like the barrel, RIS handguard, silencer, enlarged charging handle, and sling swivels are metal. Steel parts include screws, pins, mock bolt carrier, and shell ejection port, ensuring long-term structural strength.

ESA™ – Easy Spring Access System

Specna Arms’ signature ESA™ Quick Spring Change System allows rapid adjustment of the replica's muzzle velocity without tools or gearbox disassembly. Simply remove the stock slide to access and replace the spring in seconds. This flexibility is ideal for adapting to indoor CQB or outdoor field limits quickly and legally.

The ESA™ system ensures you maintain optimal performance and safety across any airsoft scenario—without needing a workshop or technical experience.
