@Love2shoot , I am going a different direction: You can get a S&W all day for $599. A Colt 6920 is $850. $150 difference between an "entry" (BTW, I hate that word) AR and a "you'll never need another" AR. People spend more just upgrading wheels on their car for cosmetic reasons.
I am not knocking S&W; it's fine. To me it's a matter of the negligible difference in cost and a large qualitative leap.
Also, I love Barnes, but once you get to that price point, you also get several awesome options: BCM, Sionics, etc.
I like your advice Chuckman, but your math is bad. It's a $250 difference.
I've chimed in on several of these threads and I am going to summarize my thoughts below based on pricing tier. Now if you're willing to shop for a used AR (and I have bought MANY and have had wonderful luck/experience) then you can get a lot more for your money. Also, does $800 need to include an optic or just the gun? Is there a preference for free float rail vs fixed FSB setup?
So if you're only looking at it from a best gun for pure dollars perspective AND you don't want to build, and this does not include optic or irons:
$500 - S&W M&P Sport II, or piecing together an Aero gun (very easy right now to get a complete Aero lower for $250 and then an upper for $250-300, but you may edge closer to $600)
$650 - Aero Precision, buy the lower and upper separate
$750 - Colt LE6920 (OEM 2 is under $700 right now shipped but you'll need to add rail and buttstock, which would be difficult for $50, but you'd have an OEM colt with a free float!)

$850 - LMT SPM Carbine, includes all furniture and super nice fixed rear sight.

If it were me, right now, and I only was going to buy ONE AR to shoot and have for damn near ever, I'd get the LE6920 OEM 2, find a nice rail that uses the standard barrel nut (556 tactical had a CRAZY deal on their 12.3" Keymod rail made by Samson and I bought one, like $130 I believe?) and whatever my favorite Magpul buttstock was. Get a set of MBUS from Palmetto right now for $50 shipped, and then save for a Aimpoint Pro, or Steiner P4xi 1-4 variable if you want magnification. Boom, done for under $1,500 with a gun that'll be fun out to 200 yards and almost never depreciate.
Since I called out Chuckman, let me check my math:
Colt LE6920: $710 shipped
Transfer: $25
Rail: $125
Furniture: $75
MBUS: $50
Optic and Mount: $350-500
Total $1,500
Or:
LMT: $850 shipped
Transfer: $25
Optic and Mount: $350-500
Total: $1,375
So get the LMT
