Here is a MVA 107 LR that cane on my Shiloh ten years ago it's the same as the mid range just shorter. If you look at the top of the staff it has sharp corners but the ones you get now the top is rounded. Also the screw on the base holding the staff is screwed in from the left. I think that sight is a later sight then from before 2000.
