I have a S&W M&P15(standard M4 style), a CMMG, and a DDV4. All are great rifles. My favorite and the one I vow to never part with is my S&W. I started shooting it to save from wearing out the DD, now it is because I like it as much. The accuracy in all three is relatively equal, none of the three outshine the others. A Colt is a great choice, I really have nothing bad to say about them. Others to mention are Spikes Tactical, LaRue, LMT, Noveske, Knights Armament, and BCM. To me my personal pick would be the HK MR556. It is my dream AR. Whatever you decide, I am sure will serve you well. Enjoy and keep us posted.
