My experience with full auto is limited to the few times someone let me fire theirs or I rented one. For to blanket an general area at 100 yards i could do that with a rented Thompson machine gun. At real close ranges things like sten gun, MP5, Owens, or a BAR are devastating or so it seemed relative to the dirt they kicked up. I think FA capability would be a nice to have, but hard to beat aimed semiauto if you want to kill. It is at point blank range that FA appears to really be great, especially against multiple opponents. It is my understanding in FL that one can not legally CCW a registered NFA machine pistol which there were at one time some people doing.The Ole " Spray & Pray " never worked that well for me......A good trigger and staying on the trigger and not slapping it yields better results for me.....YMMV
Oh Hell, Now they will try to Outlaw Index Fingers !!!
