Colt's got a brand new AR made specifically for competition shooters, and I was able to get a look at it at the 2012 NRA Show in St. Louis. The Colt 3-Gun Rifle features 28-inch stainless barrel chambered in .223 Wild, capped with a Surefire brake that doubles as a suppressor. One of the coolest features is Colt's patented adjustable gas system. Rather than worry about whether or not you have an Allen wrench, the system can simply be adjusted by hand, locking at every sixth of a turn and offering 24 positions: open, closed, suppressed and everything in between. The Colt 3-Gun Rifle has an MSRP of $1,999.
