My father inlaw has a 1919 semi that he purchased from Ohio Rapid Fire and it will not run. The weapon will fire two rounds and eject them fine but it will not feed in anymore. I can hand cyle an entire belt with out issue. But when firing it will not feed. Ive set head space over and over again with no positive results. The correct links ar ebeing used as welll, this is a 308 izzy.
