If you want my opinion, get the billet set like bwaites mentioned, unless you have the tools to true-up regular forged uppers. I'm going through a bunch of uppers right now and truing them with a lapping tool, and they were way off before I chucked up the tool to check them.
You basically got a custom engine component meant for racing, and are considering mounting it in a bent Chevy engine compartment that was mass-produced.
The billet sets or a lapped upper are what are appropriate to complement your barrel. If you want me to do the work on your upper, I can do it, make sure everything is trued up, concentric, lap the bolt to the extension, blend and polish the feed ramps, radius your ejector, tune the extractor, bed the extension if needed, test-fire, and send it back to you with your choice of 6.5 Grendel Reloading Handbooks or not.
I can also Cerakote the upper, barrel, gas block, gas tube, etc. What muzzle device do you have, and what threads did you go with?
