This might help the “bullets on target” problem I have with machine guns but I still am put off by the cost of feeding such a device. At 1000 yards with my “Spud Gun” (some call it “insanely accurate”) will deliver a bullet just as accurately and with as much momentum as I could with this sub gun at 25 yards and with far less chance of receiving return fire.
It is a neat engineering advance in guns though. I applaud them for their ingenuity.
I just called it a “God-switch.”
