Yes, this Leupold Standard EP lens cover does fit the eyepiece (optic end) only end of the RDS Red Dot Sight (RDS 34MM). (If you are buying this lens cover for Leupolds Red Dot Sight, then you need part #59040 for the objective lens end of the sight) which is slightly bigger. Yes, it is more expensive that getting some cheap after market little rubber bungie cord cover, but this lens cover will last you a lifetime and you can pass it on to another generation. I have another set of these flip up alumina lens cover on another Leupold scope and in my opinion they are worth it. They thread into the scope eye piece and softly flip up and close quietly as well. I live and hunt in the Pacific North West where we get more than our share of rain. Nary a problem keep my scope dry and from getting beat up by tree limbs and the heavy brush.
