Went to the range with my buddy and he used his rem 700 AAC .308 with the 20inch threaded barrel. It had the hogue stock. His rifle was grouping right around 1.5 to 2 inches at 100 yards depending on ammo (3 shot groups with all being 168 grain FMJ, assorted premium ammo, and two different handloads). He was shooting off of a bipod. I think the stock was flexing and touching the barrel. When I gripped the Forend I could squeeze it and feel it flex. I do not know if that model has the pillar or the full length aluminum block. I had the same model that I bought from a member on the forum that was torqued to proper specs and the barrel was floated in a BC stock. Everything else was the same minus the stock. My rifle would group between .75 (average) with the best group being .25 with hand loads. It was also shot off of a bipod. I hope I helped with my experience. Good luck with your stock search.
