CMC has not responded. I will send a second note this week. To me, failure to reset is an issue that should not be platform specific unless there are significant geometry issues in the bolt carrier and how it depresses the hammer. The Hiperfire passes (so far) dry function testing without failure. I will be range testing it fairly soon to verify. I inspected the New Frontier hammer, trigger, disconnector, and they appear "mil-spec". At this point, my only suspect is the CMC. I will update this thread with any new findings.
