I took her out today for the first time to the ranch, ran through 5 mags. one to sight in the red dot, four for fun, I love the trigger and it is a really accurate weapon, all my three round sight in groups could be covered with a .50 cent piece, most with a quarter @ 100 yards, after sighting it in I took out several jack rabbits, and praire dogs. all with great accuracy, and not a problem at all with the 556, I did not even clean it after I took it out of the box, still had the white grease sprayed in the chamber. over all I'm happy with it, and I can honestly say it is more accurate than my m-4's, as far as fun factor they all rate about the same.
