What Lysander said. Take the gas block off. The center of the rear set screw dimple should be the same distance from the shoulder as the gas port center.
Most “local” gunsmiths are complete morons, in my experience. Like, $&@# up a wet dream morons. Regardless of where “local” has been over the years. Anything past installing Glock sights is too complex. This is why I own a BRD jig, a drill press, and a MI URR. I no longer even trust local gunsmiths to do a P/W on a muzzle device that I’ve pre-installed. I take that shit to a body shop instead. At least they can follow instructions and not replace my shims with a crush washer.
Reputable gunsmiths do exist, and you can hear about them in this forum. Ned Christensen and John Thomas spring to mind. I’m sure Clint (Black River Tactical) would be able to do this job correctly, also.
