Well guys the .450 Bushmaster upper got dropped off by the mailman today, I also received my Burris 2x7x35mm fullfield ii scope. I ruff sighted it in at 40 yards this evening, my 1st impressions as i shouldered and shot it, is it should be a good little deer brush gun it's lite, short, quick, powerful, and it hardly kicks. My boy fell in love with it when he took a shot also. Mine is a 16 inch barrel and i put it on a standard Bushmaster.223-5.56 lower.
