I do feel the shrink fit method or shimming for tight fit in the upper has a lot of merit, but I have had great results with just facing the upper and bedding that I have not played with other methods. For bedding I just use red loctite, vs an actual bedding compound. After removing a couple after assembly years later I see no need to do it any other way. The loctite fills any gap and hardens into a ‘shim’ of sorts. Has to be heated and driven out to replace and I feel it does a great job.
