I have a RRA 9mm upper that I use as a training gun. It has maybe 1000 rounds through it. It recently started puking big time and I took it to the range to troubleshoot. In the final analysis, I had extractor tension issues. I retensioned the extractor as best I could but it still isn't 100%. Does anyone have experience with 9mm RRA extractors failing so soon? Any thoughts? Also, does anyone know if a Colt SMG bolt will work in this upper receiver?
