Starting over from the scratch. Suggestions for a new 6.5 Upper?

[A5BLASTER]

After 4 years and dozens of possible loading combinations, I've decided to start all over and get a new upper going on my AR15. I still like the ballistics of the 6.5 Grendel, so I'd like to get another upper but not the brand I just sold.

So,
Who's making respected tight grouping uppers these days that you can recommend; not from a "guy who knows a guy who read a story on line" but from your own hands on the range experience?
If it ain't sub MOA, it does not have a place in my gun safe. I've been there and done that. My only exception is for the 450 BM since it's a under 100 yard gun for brush and blacktail deer.

I want my next 6.5 to be a tack driver, not "improved cylinder".

Your suggestions please.

First we need to know what kind of barrel did you just sell?

That way we can give suggestions for a better barrel.
