So now that I've got this AR, what are the general recommendations for upgrades for it? I don't plan on trying to turn it into an uber sniper rifle or anything like that, but I would like to get better than stock performance out of it, good enough to handle well at a match. So far all I've done is added the rear MBUS and picked up a couple PMAGs. And yes, I'm sure this thread will be full of "You need to get this" and "Only homos get that, get this instead". I'm just needing some choices to decide from.
