I just recently purchased a BT99 shotgun, 34", with a laminated stock , serial number shows MR I take its a -2007? I saw Browning had something called shotshow special Laminate nickel plated, or is this gun Stainless? It does not say stainless in black letters on barrel that I have saw on others? And the complete rib is also stainless color like the rest of the gun. Any info appreciated.
