They match each bolt to a specific rifle and they also test fire the rifle. There is NO WAY IN HELL that a rifle left the factory with a bolt unable to close. It's a 100% certaintly that whoever installed the bases has a screw protruding into the receiver. I suspect the OP discovered this and this is why we haven't heard from him.

I know of no retailer who would take a scope in and exchange it, be it Leupold,Zeiss,etc, they have to be sent by the owner to a repair facility.
