LRRFP52,
Thanks for your thoughts on this. I've read an awful lot the past month waiting on parts for my build. Barrels seem to be the largest contributor to accuracy along with good triggers. I've seen several threads on the upper being square to the line of bore, and also think that can be a contributing factor to broken bolts, along with hot loads, and poor fits on the bolt to barrel extension. I guess I'll be checking my upper first and then lapping the bolt second. I'm hoping that the fit is tight enough on the upper to barrel extension that I don't have to worry with bedding with locktite. If it's a loose fit I may try it first for accuracy and then bed it afterwards if accuracy is not accecptable for my hunting needs.
thanks again,
CC
