@tdbru, I have an 18? upper with the group buy barrel and a 12? group buy barrel. It just seems that if I am only going to shoot paper at 600 yards, 556 is better. At least per my calculations.
I might just keep the 12? Grendel for hunting, sell the 18? barrel and build a 20?-24? 556 for target practice at 400-600 yards.
