I am relatively new to AR's and currently own a Colt LE6920. I am considering buying an AR chambered for one of the popular short action loads. I am pretty well set on a .308 but would consider one of the other rounds using the 308 as a parent case. Due to availability and cost of ammo I have just about eliminated the other calibers such as the 300AAC, 6.8SPC, etc. My entire working career has been spent supporting US industries so I have narrowed my search to rifles made in America so Armalite and most of the FAL's are out. I don't intend to drop a load since the primary purpose is target shooting and home defense (preferably <$2K). With that price point KA, LMT, Larue, and Baer fall out of the equation. That leaves Colt, CMMG, RRA, S&W, DPMS, and Remington as well as a few small manufacturers I haven't listed. Can anyone provide me with feedback you have had from direct experience with any of these that would be helpful in making a decision?
