I am finally breaking down and seriously considering an AR15. I have heard that you should stick to the ABCs (Armalite, Bushmaster, Colt) and skip the rest of the brands. There must only be a zillion choices. I would like to stick to mil spec so that I could put that Beowulf upper on later or whatever. I don't have an immediate use for a 5.56 so would be happy with a 9mm for plinking. I don't have an immediate use for the .50 either but pig or wooly mammoth hunting does come to mind. I might even go for 7.62x39 as then I could share ammo with my Yugo.
Assume that money is an object to be considered as apposed to the last post. I am open to suggestions.
