Bought an essentially new 75BD from a gent in CO as a companion to my 75D PCR and it's a real sweetie! Already put the half checkered coco grips on it from CZ Custom along with the rubber mag bases. I'm having a real time installing the mag bases though, as the hole in the bottom of the rubber base is slightly smaller in diameter than the hole in the original metal base plate. Any tricks to getting the indexing nub seated in the base plate hole?
