I've got a question.I'm looking at a BPS Cantilever Game Gun in the catalog and online.I noticed the rib on BPS guns start on the reciever.My question is does this require Browning to take metal off the cantilever to accomodate the rib on the reciever? Which would make for a weaker scope mount. Or does the cantilever ride over top of it without any cutouts or metal removal to accomodate the little reciever rib
