I was under this same dilemma 2 weeks ago. I bit the bullet and bought the AR Stoner barrel and bolt combo from Midway. Which is the Grendel II chamber. got it all together last week and took it to the range with both Hornady factory AMAX and SST ammo. both shot less then 1MOA groups right off the bat and will only get better with a better trigger, more trigger time, and handloads. feeding and extraction was not a issue either. The rifle performed flawlessly.
the reason I went this route instead of with Blackhole was because the bolt was included and the barrel was head spaced to that bolt so in my eyes there was chance of getting the wrong bolt with the wrong barrel and the headspace not working or the ammo not feeding/extracting correctly.
