Okay, lets ask you guys as I love seeing what people like. I am about to buy a new upper for my AR. I want a 24" Stainless Steel free floated barrel. A-3 Flattop (I dont need the bolt carrier group nor the charging handle but if it comes with one, I can always use it). $500 or less is the pre-req. (wifes rule....SHE just bought an M-1 Carbine taking away from my AR fund). So, what should I get and where should I get it from?
