Remember when I deal with a rifle it is rarely a specific case but more often a generalized case for production run numbers.
We have a few advantages in building such that we can change the tolerance of the extension to reciever fit. LRRPF52 suggest a tight fit and we typically have a press fit in this area, but in the shop we can push these together when it is not practical or easy for a home builder. The loctite follows the same rational. We cannot afford to have a sample of rifles shoot badly so everything gets loctite. This is not to say it needs it, or that different parts will demand the same solution, it is generally the observation based upon production.
However the advantages also have a down side. Rifles become generalities not specifics. Variation can provide problems which the home builder will easily solve but which we cannot tolerate.
