Needing a 6 br norma go gage, but am unable to find one. I looked in brownells, all they listed was 6 br. I figured this was the old rem br. Midway had part numbers for ptg reamer and go gage for 6 br, but under 6br norma they just listed reamers. Do the two 6 br, rem and norma, measure the same from the datum point? and there fore use the same go gage between them? Thanks for any advice.
