What does it take to build an accurate AR upper? I imagine a high end barrel helps. What else is important?
ammo, barrel, trigger, optic. in that order. at least for me.
What goes into an accurate AR upper?
Ammunition. What does “accurate” mean to you as far as caliber, group size, number of shots and distance?
Even the cheapest of junk AR uppers I have shot do better than the old “pie plate” rifles my ancestors used, effectively. So quantification might help answer your question. Knowing what your expectations are.
Sub MOA with something like 6.5 Grendel. I can shoot and I can hand load if factory stuff isn't what the rifle likes.

Never had to lap an upper to achieve sub-moa accuracy.

1. Barrel
2. Ammunition
Everything else (in AR platform) just gets you minuscule, incremental improvements.
