WE USA Full Metal KATANA II M4 Carbine Advanced AEG Rifle (Q.S. Gearbox) - LE Stock

The WE-Tech KATANA system is a revolutionary concept that utilizes a replaceable upper cylinder unit much like Systema's PTW rifle. The innovative cylinder design allows for simple, easy and fast swaps of the upper end of the gearbox making the rifle adaptable to all scenarios of Airsoft gaming. The cylinder housing is CNC machined from a billet of aluminum providing optimum strength. Stainless Steel nozzle and end caps, a high tension internal spring, and the reinforced polycarbonate piston make the KATANA cylinder rock solid. The lower gearbox section is completely constructed of high strength metal alloy with steel bushings and a steel alloy gearset providing great reliability.

Externally the metal receiver and full metal barrel assembly provide a realistic, durable feel furthering the training rifle experience. The detachable carry handle reveals a railed upper receiver for mounting optics and the working mock bolt catch allows for easy hopup adjustment. Cylinder replacement is made easy by simply removing the rear receiver pin.

The WE-Tech KATANA system is an extremely adaptable platform that will serve you well in any Airsoft situation.

Look for the WE USA logo on the WE Katana when you buy a Katana. The WE USA logo indicates that this product is directly imported by the distributor, not a second hand product, with the newest specifications, newest updated internal parts and quality controlled right here in the USA on top of our dedicated / exclusive QC process at the WE factory.
