I ordered the Boss rib on my lovely wife's Galazan Inverness just because it was different and Tony's display gun was so well done with the Boss rib. I begged to be exempted from the high price of that option, but Tony wouldn't budge. Her gun came in optioned to the hilt, even though the rib was my only request. Apparently, Tony owed Linda a favor and it came through on this wonderful gun. I wish I had ordered a pair. The shooting qualities of the Boss rib are no different from any other sighting plane.
