You can get either a Weaver rail or a Picatinny rail for your Ruger Mark II. Check which one your red dot needs. My red dot only fits on the Picatinny even though the red dot product info states it'll fit on a Weaver rail; I think the issue might be that Weaver rails aren't all standardised whereas 1913 Picatinny rails are all the same.
