heya mehavey--I'm still very curious about what the "no-go" headspace measurement is for your CMMG AR in 350 legend--I'm almost certain the reason for the failure I experienced and the near failure you had was due to excessive headspace that allowed for the head of the case to be unsupported while fired. The tolerance for the ptg gage is 1.714 and that is what the savage axis tolerance is made to--but my Faxon set-up went with the default SAAMI spec max of 1.72 which is what allowed the area above the web in the starline case to be unsupported IMO.
