I will save up and buy the best. I just want something that is a good shooter that is fairly easy to maintain.
Well, from a cheap SOB pragmatist (and there are few of us left), iff'n it were me:
1. I'd get an M4 style-for what you say you want it for, a carbine is plenty accurate enough, light, and is a pretty good "do it all".
2. You want name, quality, with no muss/fuss-find a (new) Colt LE6920 for under $1300-they're out there.
3. If you really want to save some money with no hassle, RRA has a good reputation-'course, there are going to be the usual haters out there!
If you want to get deeper than that for your first AR, the previous link I posted should keep you busy for a while!
'Course, everbody's gonna suggest a "specialist" AR etc, but for your stated needs, I'd recommend starting out with the M4 style, and use the money you save for optics, etc.
Iff'n you do want a boutique AR, I"ll talk to my relative-he's got an AR with a heavy stainless barrel and 'bout 7 lbs of weights in it-only weighs around 16 lbs!
Gotta luv those bench rest boyz!
