Mike, a cheaper option would be this adapter >>>> amazon.com/gp/product/B01ABW7GS0/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 --------or this one, depending on the length you need >>>>> https://monstrumtactical.com/dovetail-picatinny-rail-adaptor/ ----- these adapters will allow you to mount your scope. ----If you go the other route, make sure you get the right size rings.
