Sorry but they are not. I tried a 2BA bolt in the rear guard just to see and it is not the right size. I found a thread somewhere that informed me that the manufacturer's thread could be retapped to 2 BA quite easily though. Maybe that is what you have come across. And the front stock screws are certainly not 2BA. 4mm fits but I doubt if that thread form is the original spec.
