Does anyone know of a Weaver type scope mount that I can mount on my 500 that will accomodate a BSA red-dot scope? I have purchased a Weaver type 417M type but the BSA red-dot scope will not fit. Not enough notches/grooves milled in the mount. I guess I could mill more notches in the 417 mount but I would prefer to have one that will work on any type of red-dot scope. I always start out with an in-expensive scope and then graduate up if the red-dot scope works out okay. I did this with my Ruger Mark II target pistol. I got a B-Square scope mount and mounted a BSA red-dot scope and it worked fine.
