I thought it was a buffer issue, just wasn't sure which way to go. One thread on here recommends heavier buffers for reliability, that may have been for feed issues. Another recommends to do the one round lock up test and if it doesn't lockup go lighter. I'll keep in mind the bolt catch spring thought too, did not think about that.
I'll pick up a H buffer and see how it cycles.
Thanks again.
