Cimarron 1892 - Marble Tang Sight ?
I have a Cimarron 1892 Short Rifle (Mfg. by Amrni Sport) on which I wish to mount a Marble Tang Sight. The Marble Improved Peep Sight #991001 fits perfectly. However, the installation screw set recommended by Marble is not correct for my gun. Specifically, the forward sight mounting tang screw supplied is not the proper diameter. It is slightly too large.
Does anyone know the correct Marble sight mounting screw set for my gun or can anyone tell the the correct screw diameter and thread pitch for the factory drilled and tapped tang sight mounting hole?.
