Questions about my first AR build???

LRRPF2,

Thanks for the link. Yes I'm familiar with "blue printing" a bolt action even though I haven't done it. I probably won't do it with the Grendel, but I will put a little dykem on the lugs just to see how much contact I have. The main reason I probably won't do it is I don't want to mess with the headspacing on the bolt/barrel combo. I've read several threads on the subject now, I'm not sure how much it does for accuracy. However, I am convinced that it can be a contributing factor to broken bolts.

Nugginfutz,

Thanks for the diagram. As they say a picture is worth a thousand words. I'm not sure why, but I was visualizing using the spring and the back half of the case.

thanks,
CC
