I am trying to find out who manufactures the M16 Maximum Headspace Gage, Ordnance Part Number 7799734, NSN 4933-00-070-7814. Does anybody know? I know that Brownells sells them, but they are not pre-cut like the government model. I see only one place to buy them, but I would like to see if I can buy from the manufacturer or from someone other than billricca.com. Thanks.
