I'm sure I'll later upgrade some of the parts of whatever AR I get (better trigger, ambi controls, charging handle, sights/optics etc)

Saw a few melonite/nitrided barrels, some googling tells me that a lot of people think it's a better option than chrome lined.
it's not that there is anything wrong with a home built gun. nothing wrong at all, in fact. I do it at least once every other month or so.

what a factory built gun can offer is fit and finish of teh final product.
