Is there a way to check headspace without a set of Go/No-Go Gauges?
Would using a depth micrometer and measuring from the rear of the barrel extension to the base of an installed cartridge be valid? If so what is the dimension and tolerance +/-?
In the past I've cut chambers for bolt guns but never for an AR. For the AR, is the barrel extension on the barrel when cutting the chamber? Or, is the chamber cut and then the extension installed?
