Anyone in the Triad have a means to check headspace?

[Cucamelsmd15]

I have been chasing my tail with a 308 AR-10 for a year now that simply doesn't shoot. It's a Ballistic Advantage barrel in a PSA AR-10 platform, and it's never shot better than 1.5-2 MOA. I'm to the point of checking headspace and whatnot now before I ask BA to replace it.

I am close to WS but will gladly come to you.

Sorry don’t have .308 head space gauges. But tell us what you have done to this point. We may be able to suggest something else to check or try.

Save a half dozen or so of your fired brass, same of your sized brass. compare the 2.
