Full description


This Airsoft Electric gun is based on the widely popular and successful M4/AR-15 platform, and features a modular free-float handguard in combination with excellent external and internal construction for a solid and reliable AEG for both beginners and pros alike.

The front of the rifle features an Alloy flash hider which can be removed to reveal a 14mm CCW thread; perfect for the installation of flash hiders, suppressors, tracer units and other muzzle devices to make your AR stand out from the crowd. The free floating handguard is also made from Alloy and is a modular design which allows you to place rail exactly where you need it, to save on total weight. The handguard has a full-length top 20mm rail which runs down to the back of the receiver, and short side 20mm pieces. Further rail pieces can be installed where you like on the handguard for more accessory space should you need it. The top rail comes out of the box with a set of spring-loaded flip-up ironsights installed to use as a main sight, or as a backup to another sight. The receiver is made from a tough Nylon Fiber Polymer, and features USMC markings and logo. The fire controls will be familiar to anyone who has used the AR platform before. The RIF is rear wired, and features a Mini-Tamiya connector inside the sliding Crane Stock, which offers plenty of space for a Crane Stock style battery. The buffer tube allows quick access to the main spring, for a truly 'Quick Change Spring'. The ESA™ system reduces the time taken for a spring change to around 45 seconds once you know what you are doing, and makes this RIF great for those who play at fields with different FPS limits.

Internally the replica features some great components, such as a Rotary HOP Unit for ultra-precise control over your HOP settings, coupled with a 6.03mm Precision inner barrel for remarkable accuracy and range. Other internal parts include 8mm bearings, Steel gears, several anti-reversal latches and a Polycarbonate piston with Steel rack. Included in the box is a 380rnd high capacity magazine, which is filled from the fill window at the top and wound from the bottom to feed BBs into the RIF.

If you're looking for the perfect starter gun which offers more out of the box than most Airsoft Electric Guns, and has a tough exterior construction to go with it, then the Rock River Arms SA-C06 CORE Carbine is the perfect choice.
