need to identify bolt? - tackdriver - 09-17-2013
I have a brand new stripped grendel supposedly AA bolt. I figured with all the builds going on it would be a good time to sell it. I do think it would be wise for me to know the head space before I sell to someone. Could some one tell if there is a halfway accurate way to get this measurement with just a pair of micrometers? Any info would be helpful

you need to know the face depth AA is .136" 7.62 in .125"

My AA bolt has a big AA on the side of it. I don't know if they are all like that though.

This doesn't have any identifying marks but foes appear to have the .136 face. I have come to this conclusion by measuring depth w/calipers. I know that can't be exact but I am sure enough to bet on it.
