New to airsoft? Here are some safety tips for airsoft guns that we recommend following.

The Knight's Armament URX 3.1 Rail System is a freefloat system that allows for the installation of tactical accessories such as lights and optics. The modular design of this rail system keeps the weight down while allowing you to have rails where you need them. Five QD Sling Swivel Mounts are present on this rail. Two are located near the receiver, and three are located near the front, which gives you multiple options for sling application. This RIS system is features fully licensed trademarks from Knight's Armament Company, and is probably one of the most realistic pieces of kit you can find. The two piece design allows you to drop out the lower rail in order to accommodate barrel mounted accessories such as a grenade launcher or Master Key shotgun. This rail system is compatible with most URX 3.1 accessories.
