OK AR gurus ... need your help.
I've been shooting an AR forever recently got into building a few. First was fine but I made the mistake of buying a used barrel for my last. Shoots just fine but I can close the bolt on the NOGO but not on the FIELD gauge. Trying to figure out the plan. I tried a few bolts but they all close on the NOGO.
I've thought about just adjusting my sizing die for the proper headspace the same way I do with the .308 loads for my bolt gun but then I'd have to load separately for both ARs which defeats the purpose of finding a load that they both like. I suppose I could try a headspace setting that is a compromise but that still seems like a guess and I'd rather fix it rather than always wonder if it's OK.
Any other options other than replacing the barrel?
I searched the Semi-Auto and Gunsmithing forums and don't see a whole lot of people actually fixing headspace issues in ARs.
