I thank you for your brutal honesty. However, like you and several others have suggested, I find purchasing an entire unit (ie: the entire gun) unpractical because drains the pocketbook quick in one hard blow, whereas the "not-so-much a build-build" I can buy the lower, tinker with it for a while, buy the upper- install, then more tinkering- sights/optics, etc. Everything in steps.
I get where you are coming from. I can relate to the need to spread a purchase out a bit, although in general I would say that the thing to do is to save up...takes longer, costs less. But assuming that's out of the question because you want something in your hands sooner rather than later - and I can relate to that too - this is what I would suggest:
From the EE:
a stripped Aero Precision lower. Pay maybe $150 shipped, preferably less.
a milspec receiver extension & buffer (that is the "buffer tube" and guts) I would contact ABHobbyist because he has an insane amount of parts and you might be able to get the tube, buffer and spring from him in one go and pay shipping once. Maybe a hundred bucks or so? I would think not more than $125 for quality stuff.
an A2 grip because you will be able to find one on the EE for a nickel and they work fine. In fact I saw a knockoff A2 for $5 there recently, and the genuine article is only worth about $15.
From One Shot:
a Daniel Defense LPK , $100
Magpul MOE stock, $60
Complete lower including shipping and taxes, something like $500 and easy to put together
For an upper I would buy a complete unit. That Stag is pretty good. There are uppers on the EE all the time. For $700-900 you can get something very good. Brands I would look for are LMT, Stag (but ensure it is a 5.56 1:7, not one of the cheap barrels they sometimes come with), I hate to say it but Spike's, Daniel Defense, Colt (but it will be expensive)
You could also buy a complete new NEA upper, and see if they'll cut you a bit of a deal on buying a set of Troy sights. The CQB upper will run you around $750.
Alternatively, when you order from One Shot, buy a set of Daniel Defense fixed sights at the same time for $130.
That puts your build in the $1200-1400 range and you will have a gun built of quality parts. That's the cheapest way I can think of to build an AR that I would personally be proud of.
