I will be making my first AR purchase by the end of the year. Based on what I have read on this site I have narrowed it down (I think) to two choices. Colt or DD. Based on reputation and initial cost they seem to be a good place to start. That being said, what kind of configurations are recommended for beginners? My initial thought is iron sights and go... maybe a rear sight that flips down, but other than that I don't see the need in spending the extra money right off the bat.
Any recommendations on initial setup? Any sources for good information that I can read through? Any recommendations at all? Primary intended role of this rifle is the day that I hope never comes, what ever it may be.
