I've got a M1918 Winchester BAR that was converted to an A2. I'm in the process of making it all original to M1918. I bought a barrel from someone at Knob Creek, installed it and the headspace failed. I gauged the TE and both the barrel that was on it and the barrel I bought were 3 and 5 respectively. So, I got a new barrel. Put that. Head space fails according to method used here Page 11 in PDF: http://www.forgotten... bar manual.pdf
I have a NESA that I used for reference. Using the same field gauge, same bolt linkage, my NESA passes, the Winchester fails. I'm trying to figure out what I need to do to fix this. Are there different size bolts I can use?
