I wonder what CT (Connecticut) AR 15er shoot these days. As you know, CT is one of those "Ban State". I think the availability of legal AR 15 is limited. I'll buy my first factory-built AR 15 soon but am confused by the various configurations of AR 15 from different AR makers. After reading the threads on the forum, I narrowed down my choice to BCM, Noveske and LaRue OBR or PredaOBR. Any suggestions please? Thanks.
