I would also look at SOLGW. They undersize the barrel extension slightly for a tight barrel fit (like BCM) which people say helps with accuracy. They also slightly oversize the lugs on the upper so you get a nice tight fit (instead of needing tension screw in lower) with their lower, or most others

BCM also has a new upper out which should be more rigid that a standard milspec. They also undersize for tight barrel fit. If you are on a budget you can also pick up one of their normal blem uppers for under $70. I have bought several and like these
Solid advice right here.
