I have been lucky with the purchase of a new Breda B12i shotgun with 24 inch barrel. Does anyone have the thread pitch for the scope mounting holes drilled in the receiver of the B12i ? I have a GG&G picatinny rail that has 8-40 screws which are too large in diameter for the holes. I am thinking that 6-48 might be the right size. I would like to try an aimpoint T1L micro red dot on the shotgun. I mounted a Briley +8 carbon fiber mag tube, and an A&S Engineering trigger guard. About all you can do to this great gun. Tnx for any professional responses. SFC Ronald "Kilmore" Moore in Salt lake.
