Hey...thanks for all the replies.
East county - oops, should have been more specific - Multnomah county
Thought about Allison-Carey (sp?) , but heard they were not 'black' gun friendly? So that pretty much answers the bolt gun question.
I had a post-ban barrel laying around and finally put it on a CMT upper and wanted to check head space without dropping $50 for gauges, and get the end of it threaded, too.
I thought about Tornado, but it's a bit inconvenient getting out to Hills-burrito right now, too much over-time at work. And I'm not sure if they do head space checks or not.
I read on here a while back that if the barrel is new (yes), the upper receiver is new (yes), and as long as I installed it correctly (I think?) then head space should be good to go. But I think I'd like that warm and fuzzy feeling that knowing brings.
Anyways, thanks again for all the replies. Much appreciated.
