We already wrote about the cooperation between WE and Umarex some time ago, and nearly a year ago a video with a prototype of the G3 rifle replica suing a GBBR system went online.
A photograph of the final product appeared on the profile of the WE company on FB with a description in which we can learn that the rifle has a full markings of the real rifle (Umarex license), the magazine has a capacity of 30 BBs, the rifle is made of stamped steel and plastic. The declared muzzle velocity is 450 fps.
