I read a reply in one of the threads on AR-15.com that said the headspace on an AR is a moot point, unless the barrel and/or bolt are seriously worn out. I'm asking because I want to pick up an AR parts kit and 0% forging and I have been unable to find any headspace instructions.
I looked around and found a picture of the breech of an AR barrel and a bolt. I can't really see any way that headspace would be adjusted, short of dressing all the back edges of the lugs on the bolt. This would only increase the amount of headspace.
So here are my questions... Do you just slip in the go & no-go gauges and see if it's right? Is headspace adjustable on an AR-15? If so, how?
