L. Brown.. I think it is just the way the pictures appear. Since the barrels, lugs and monoblock seem to be all one piece there really isn't a rib (per se) under or above the barrel, is is just deeply milled between the barrels.
What catches me as strange is that the first time I mounted the gun I thought it has a Mid Bead half way up the barrel that I hadn't noticed but in fact with teh "Plume" on the Breech end and front bead set way down between the barrels is creates an optical illusion making it seem the front bead is much closer than it actually is.
It is going to be very interesting shooting this gun since it appears the barrels will actually obscure the sight picture as compared to a SXS where the Rib actually puts the front bead above the barrels. Of course I shoot so poorly it won't make any difference.... LOL
Another couple of weeks and it should be nice enough here to venture out to the range so see how it shoots.
Any additional thoughts folks have will be greatly appreciated.
Thanks!!!
