Neither Krieger or Bartlein sell Grendel drop-ins. You can however buy 6.5mm barrel blanks directly from them and find someone reputable to profile it for you. Then assemble it yourself or commission them to do the whole upper.
Another option if wanting to assemble the upper yourself. Lilja sells Grendel drop-ins and they are Olympic-quality match barrels. In an AR I'd say they are on par with Krieger.
If shooting from the bench in an AR you cannot really go longer than 24", however 18 or 20" will do fine, be reliable, and easily hit 600yds without issue.
