OK, after YEARS of shooting bolt and lever action rifles I am looking to purchase my first "real" AR in 5.56/.223. I have looked at Anderson, S&W, Palmetto, and Springfield (Saint)... I am looking to spend around $800ish and certainly would use any change for ammo. I have a scope and mount ready to install.... I am guessing the Saint would be the top pick but in your experience is there a RED FLAG associated with buying any of the other brands... I am not interested in a "build" per se as it is out of my field of knowledge. My AR would be for range use, hunting large game if they ever approve that in Pennsylvania, and of course the choice in the unlikely event of any apocalyptic bug out. Thanks for your indulgence and knowledge... Much appreciated.
