Back in the Great War, stationary rifle batteries were used for harassment fire, hooked up to tripwires to protect against infiltration and whatever imaginative thought came to mind. For those who aren't familar with rifle batteries, they were devices to which several rifles could be affixed. The rifles would then be loaded and cocked with the trigger activated by a lever.
Well, I was musing about how a cam shaft works in an automobile. Why not bring back the rifle battery but use semi-automatic rifles (Mini14s)? The battery would be operated by an electrically powered camshaft and the rate of fire could be controlled by a knob. Somewhat like the old Calico mounts for the M1 carbine or 10/22 but depending on the length of the cam, you can have more than 2 guns. Perfectly legal too.
