You already know my approach but I'm of the opinion that the lower receiver itself doesn't matter that much, but I've only used 80% lowers. I don't think my 80s are anything special but I've been careful to do my best on them. A trigger group you like is always a good thing. A fixed buttstock yields more accuracy than a collapsible one but what fits you might not fit your better half.
I think the real magic is in the uppers, using quality components and carefully fitting the barrel to the upper receiver. I like the bravo company upper since it's slightly undersized and thermo fitting the barrel to the barrel to it. I've only used the bcm blems since I don't care how it lt looks. Clocking the barrel properly is important so that the gas tube doesn't touch the barrel nut and upper receiver is very important for accuracy.
Although I wouldn't shoot critters at that range, 600 yard accuracy should be childs play with quality bullets such as Berger, Lapua, sierra, etc. The Grendel should stay supersonic out to 1200 yards with 100-120 grain bullets.
