Good sight bad mount - Burris SpeedBead Red Dot Reflex Sight

Good sight, have used them on other guns. Still trying to get this to fit correctly. You can't just put in between stock & receiver and tighten up. Uses foam and thin piece of metal. I tried to research others problems mounting to avoid complications myself. I have a synthetic stock & have found it needed to be notched to sandwich metal mount, but with foam almost impossible to get notched correctly the 1st time. Eventually if I can get positioned correctly I know I'll like it, but no wayI can recommend it as is.
