The Czech-made Calibre Classic series also had the "R" logo, but it's not one of those because (as far as I know) they all had maple tops.
The electronics look cheap, I'd assume BC Rich use better quality parts on US models.
Beyond that, I have no idea I'm afraid.
Not sure of the heritage of the guitar - although seller says made in 2000, whilst still in hands of Rico family
Elecs are standard EMG parts so no judgement can be made there
Don't think the R on the headstock has always indicated USA made though
Company has been through so many changes of ownership that different policies came in at various times
Also if was USA high end then the seller wouldn't start the bidding low with NO RESERVE surely
Older USA Riches didn't have recessed backplates
The SPC control on there is an OLD one (well over 10 years old) - but could have been added later
It looks like a nice guitar however - worth a few hundred at least no matter where it is made
