Welcome. There's a thread with all the different manufacturers, upper suppliers, barrel-makers, etc. if you search. The search function works pretty well on this site, but will still require some sifting and reading.
The AR15 is actually a very inhernetly accurate design, since it's so easy to free-float, and drop a nice trigger into. It's probably the most affordable rifle to accurize, since there is no need to glass-bed, pillar-bed, blueprint, or do any bottom metal work on like bolt guns require.
That said, the biggest factor in any rifles inherent accuracy will be the barrel. This is your accuracy recipe starting point, if accuracy is your goal. Everyone has different standards of accuracy, and you may find that a standard barrel satisifes yours, while seeming attrocious to a benchrest shooter.
Most button-rifled Grendel barrels are able to shoot under 1 MOA at 100yds, even for 4 or 5-round groups. The next level of accuracy is a barrel that will consistently shoot under 3/4 MOA at 100yds. Most cut-rifled barrels will do that, and usually will shoot 1/2" groups at 100yds, with a few groups larger than that, but still at or under 3/4".
Shooters who compete at greater distances lean towards barrels that hang around more at the 1/2" grouping pattern, since they are dealing more with wind-reading and distance errors that can make a difference when the shot pattern is 1 MOA versus 1/2 MOA.
