I'm looking for my first ar15 so at the moment i'd rather not build one. I've looked at different stores and websites and yesterday at at store i saw a Bushmaster XM15-ES2 16" flattop for sale. Adjustable buttstock, forward assist, dust cover etc. Had no carry handle (ofcourse) and set up for optics. The barrel had 5.56 stamped on it so it can shoot both calibers. Here are pics of pretty much what it looks like. I think it's as close to it as i could find. I have a few questions which is why i'm posting. It costs brand new for $899, is that a good deal? For a first timer ar15 shooter this will be great for me i'd assume. Compared to the other guns in the store i thought it was pretty good. I've heard bushmaster makes a pretty good gun. I'd use this pretty much for target shooting. Thoughts, concerns over these? the price?
