Hi, I'm interested in getting my first AR15 and would like to see some recommendations on a few high quality and reliable factory-built models from reputable manufacturers (i.e. Stag, etc). Can you name a few reputable manufacturers of AR15 in addition to Stag? My budget is $1K to $1.5K (without optics) and I prefer it comes with iron sights (but can be removed to accomendate optics - Red Dot, etc if I choose to later). I don't intend to build my first AR15 at the moment. BTW, I'm in CT so I don't think Colt AR15 is legal here. Otherwise, I really want the Colt 6920LE (postban AR). Is post-ban Colt legal at all in CT? How about the Sport version? Thanks for your help.
