How do you plan on securing the upper during the process? Some vice blocks put the torque on the upper, others grab the barrel extension locking lugs.
I'll definitely check the headspace. I don't have a vice to work with. I clamped the upper to a table when I did the handguard install to torque the new barrel nut. Had no issues aligning the new low profile gas block. Gun ran just as it did before after installing the new handguard and gas block.
