I have not personally been "introduced" to one. However, I also am interested in the .223. I've read up on it and have read reviews from everything from gun writers/testers to Bubba's review on multiple shooting forums...I've read virtually nothing of significance that is negative. Seems numerous people are getting sub 1" groups @ 100 yds right out of the box. It's billed as an "entry level" rifle yet it seems everyone is surprised and amazed that it seems as accurate as rifles costing 2-3 times as much. Also made in the good ole USA.
I think Dick's, Gander Mtn, Bass Pro etc, most of the big boxes may have them. I'm going to see if my local owned shop can order me one. I'd just rather by from the little guy if I can.
