Hunnicutt - January 15, 2013 The Precision Guided FirearmThe Precision Guided Firearm from TrackingPoint combines a rifle with and electronically controlled trigger with a television scope.

I made a first-round hit with it at 960 yards.Winchester\'s new .17 rimfire cartridgeWinchester\'s new .17 rimfire cartridge uses a .27 cal. case originally designed for stud-driving tools. It will drive a 20-grain bullet at 3000 fps.The RedringThe Redring is an holographic sight intended for shotguns. It will attach to most ventilated ribs and, as the name implies, projects a red ring into the aiming area. It took a couple shots to get used to it, but I seeon was hitting reliably with it.The Mk-16 Jager KarabinerThe Mk-16 Jager Karabiner from S.W.O.R.D.
