I have been looking at some of the videos about it, and machine shops in cali specifically have days that people can bring their 80% receivers in and have them done on a computer controlled mill. i think it would be cool if a machine shop in oklahoma would do this i would love to do a group buy on some 1911 receivers and ar receivers. if someone with the equipment and expertise to do this or knows someone we should have a talk and see how many would be interested other than me.
