Found this odd photo in an MP5 Enthusiast Group. At first glace it looks like an odd optic mounted in a strange location on an MP5. However it isn’t an optic. It is a contour camera. I am not familiar with Contour Action cameras or their mounts but the position seems odd. It appears to be mounted at the rear of the MP5 right above the rear endcap. It is hard to tell but I believe the camera is offset so the shooter can still use the irons. The barrel has some blue covering, possibly for simunitions training. But if that was the case, why isn’t he using eye protection?
