In addition to the metal body the gun has a metal free float quad rail system that allows a large number for different accessories to be easily mounted. The KM4 RIS was designed to give players a balanced rifle that can perform in may situations while maintaining maneuverability. The carbine length barrel and adjustable stock make it easy to maneuver around in those both on the field and in tighter spaces. The gearbox in this gun is the redesigned 2GX version 2 gearbox which makes it amazingly durable compared to the standard gearbox and nearly all aspects of the design have been improved. The crane style stock allows up to a 9.6 small type nunchuck or small LiPo battery to easily be fitted into the stock giving it an amazing rate of fire. This extra durable gearbox makes this gun LiPo ready out of the box. KWA makes some of the finest guns available for high end competition play.
