A compact and deadly M4-based Airsoft Electric Gun which features an Alloy KeyMod rail system, collapsible stock and a wealth of up-rated internal goodies, which are a cut above what you get from other beginner-orientated Airsoft Guns.

The Specna Arms SA-C08 is a compact and well-constructed Airsoft Electric Gun, which is aimed at beginners who are looking for a top-spec rifle at a low-spec cost. It features plenty of rail space as well as licensed markings from Rock River Arms, an American firearms manufacturing company.

Full description


The front of the rifle features a 14mm CCW thread underneath the standard birdcage type flash hider, which is ready to accept suppressors, flash hiders, tracer units or anything you can throw at it. The rail system is a KeyMod design with short 20mm RIS sections pre-installed out of the box. The top of this rail has a full-length top 20mm rail for sights and scopes, which runs to the rear of the receiver. This gives you the option of both rail systems depending on whether or not you would like to keep the rifle as light as possible. 

The receiver is made from a tough Nylon Fiber Polymer to make it both tough and lightweight, and has markings from Rock River Arms. The rear of the weapon features a six position sliding Crane Stock which is also where the battery is housed, and contains a Mini-Tamiya connector. 

The stock offers plenty of space for a Crane Stock style battery, either NiMH or LiPo, and is easily accessed by removing the rubberised buttpad. There are QD sling sockets for a push-fit QD sling on either side of the stock, should you wish to install a quick-release sling loop. On top of the full length top 20mm rail are a set of flip-up ironsights which can be removed, or used in conjunction with a main sight. They are a flip-up style, and pressing the button on the rear will flip them up into place.

Internally, this replica features a wealth of goodies inside the gearbox, such as 8mm bearings, a Polycarbonate piston with a steel rack, several anti-reversal latches, a Rotary HOP unit for precise adjustments, coupled with a 6.03mm Precision inner barrel for maximum accuracy and performance over a long lifespan. The RIF features Specna's ESA™ Quick Change Spring system, which reduces the amount of time taken to change the main spring to a mere 45 seconds. The main spring can be assess from the buffer tube once the crane stock is removed, which is great for those who want to be able to rapidly change their output FPS. Included in the box is a 380rnd high capacity magazine which is filled with BBs from the top through the fill window, and wound from the bottom to feed BBs into the RIF.

If you're looking for a lightweight yet tough, rigid replica which is ideal for beginners and seasoned pros alike, with a fully licensed design and a wealth of internal up-rated goodies, then the Rock River Arms SA-C08 CORE Carbine is just the ticket.
