Today I was looking through my many binders for a specific bit of info, than it occurred to me; I should share as much as I can with my CGN friends. I've asked more than my fair share of questions and I'm sure these will be of some value to people here.
These are barrel threads, mainly milsurps, some common and some oddball, also the hardness of some receivers.
