I had my son's youth model 1187 Rem in 20 gauge to a gunsmith last night to have it drilled and tapped for a red dot scope. he informed me that he would have to drill through both the receiver and the tongue of the barrel that slides in the receiver to make it work as the metal alone on the receiver is too thin. Therefore whenever the gun needed cleaned the scope and all would have to come off. Does anyone know of another way to mount a scope on this gun? I already checked with B-Square and their saddle mount does not fit a youth model.
