Already have a colt, since I think the ban will happen next year I have decided to go ahead and buy another, maybe two. Went to my local gun store today, they still have a quite a few. Of those the colts, and s&w's are gone. They have the armalite m15 with magpul furniture, the sig m400(plain jane) a couple dpms, a bunch of mossbergs, and some olympics. All where 5.56, so which would you recommend????
