My grandpa had a 308 winchester model 88 lever action that had a scope mount with a hinge on the side and could be flipped to the side so you could use the iron sites if you wanted. It was really nice because it held the scope very well and it returned back to zero ever time. I think it was made my weaver but I am not 100% sure. I am interested on putting one on my marlin 336 30-30. Does anybody know where I can get one or if any company still makes them today.
