not sure. one of the guys I shoot with is our local garand guru (has all the tools, gauges, etc etc) and has been tinkering with mine.
it's out of time. regardless of parts changed, you can stuff a timing gauge as far as it'll go into the magazine, it will NOT trip the bolt release. if the gauge is bottomed out AND you start wiggling the op rod, it'll go (when we checked it, the lug not he op rod was @ .310'....RIGHT at minimum spec)....but swapping it with a known good (SA i think) op rod didn't fix it.
