I would have sent the PF back to PF and tell them to make it to industry specifications! Don't sound "precision" to me! If they only make their uppers to fit their lowers then so be it but they need to specify that! I have built a lot of uppers and those that went on RRA lowers did so without any problems! Of course I am just a "common man"
