I am no fan of PF, however... their upper I have fit on 3 different lowers. Two PSA lowers, 3 years apart circa, and one Noreen Billet.
Could be that there is a slight tolerance stacking going on with your PF upper against your RRA lower. Don't know, and since it has been tweaked to fit, it is no longer a matter of concern.
