I had a B-Square mount on an early Mini, it's sitting in a drawer somewhere. S+K makes one that replaces the rear sight and cams down on a set screw at the rear. I had my gunsmith drill and tap the receiver for a forward mounting screw. This is solid enough to carry the rifle using the scope as a handle, but, no back up irons. Weaver used to make a similar product that offered a lower mounting position. Had good results with that one too, but, sold it with the rifle. I like Mini-14's. Fun plinkers like a 10-22 but louder.
