I asked Criterion but didn't quite get the specific answer I was hoping for. I need to check headspace on my Criterion Core and Geissele REBCG.
"We hold tolerances that are well inside of SAAMI spec with a 1.4646 go spec and a 1.4676 no go spec. I agree, the SAAMI minimum and maximum gauges do little but ensure that your rifle is within tolerance… it does not ensure tight tolerances."
So with that in mind, does anyone have an idea on what gauges would be best? I guess he's saying anything would be better than nothing and it wouldn't hurt to have some on hand for my other ARs, but I'm trying to confirm a headspace issue with this specific setup.
