I am considering getting my first AR. Not knowing much about them I have been drowning myself in internet information. I don't think I am ready to build one, so trying to find as much value for low $$ as possible. Seems like the M&P Sport II keeps coming up as a good rifle for the money, I am seeing them for around $590-$625 online (although it looks like two months ago they were going for $500-$525). Those of you who know way more than I do, what do you think? Other suggestions/thoughts?
