Normal, and what you are smelling is parkerized and anodized parts rubbing against each other.

In time, the now rougher surfaces will smooth out, and although they will still bear but against each in movement, later smoother parts  with have less friction each other, and will be less smell.

As for the worst this lot, seems to be the charging handle against the upper receiver surface track, since this seems to be the areas is is often missed when lubing (charging handle surfaces not lubed before the charging handle is reinserted back into the upper after is has been cleaned).

B/C should have been CLP lubed inside and out before it was put back in the rifle (then the action cycled a few times to migrate the CLP from the B/C to the upper surfaces), as well as the buffer and spring CLP lubed before they where installed in the tube, and guessing the part you missed was a light coat of CLP on the charging handle surfaces before it was installed in the upper before before the B/C was installed to begin with.

If you need a source of CLP, the large spray cans of BreakfreeCLP are less than $10 at Walmart.


Also to note, with the exception of the rifle bore itself, the entire rest of the rifle is both cleaned and lubed with CLP, including scrubbing the chamber with a chamber brush and CLP.  Hence CLP also has a great cleaning agent in it.  As for the rifle bore, CLP does not clean copper fouling quickly, so something like Sweets copper solvent (which removes copper fast without a lot of needed scrubbing) is first used to clean the copper out of the bore before the other parts are cleaned, like scrubbing the chamber afterwards


So to clean and lube the rifle, here are the only two solvents that are needed,
