I'm just getting around to finishing up my SnipersHide JD Machine semi-auto .308 and I'm having some issues with checking the headspace. I bought the Mega Arms .308 18" barrel for this build and when I check the headspace like John McQuay shows in his Maten build (disassemble the bolt, put the GO gauge in the chamber, put the bolt in, and it should spin) the bolt doesn't spin. I contacted Mega Arms and one of the guys over there said I'm doing it wrong. He said that I should assemble the rifle, put the GO gauge in the chamber, pull the bolt back half way, let it go and let the buffer spring seat the bolt, then make sure that the bolt closes all the way.
I really don't want to blow myself up, could someone please advise me as to the best/correct method?
Thanks in advance,
Craig
