Hey guys, I ordered a set of headspace gauges the other day, and received them today. Anyway, I noticed on the package it says "Match Specs", and I think I might have ordered the wrong set. They are for .223 Rem, GO/NO GO 1.4636/1.4666, and the barrel is a Criterion, am I alright, or do I need to send them back, and get something different? Thanks guys.
 
That's basically go and go+.003. They will work just fine. I would set your headspace to where bolt will drop about halfway on the +.003 gauge. Once torqued you should end up with around .002 headspace.
