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.
Chrome lined is fine and your barrel will easily last 15k+ rounds. Anything else is just a waste of money for an entry-level AR.

Any of the Palmetto State "Premium" uppers will suit you find and last forever. I've bought a few of them and they each shot less than 1.5 MOA with bulk ammo.
