redsox,
Try this site that found for 30-30 peep sights that are tang mounted. It might help....

On a Win94, you can mount a scope but it has to be angle eject, or if not, then the scope has to be mounted offset. I'm not sure if a reddot scope would work though... Most people have a low power 4X scope or an even lower 1-4X scope.
Then again, there are lever action purists out there who absolutely refuse to have a scope on a 30-30! I readsomewhere where a guy wrote in saying something like, "a scope on a 30-30 is like putting combat boots on a ballerina! It can be done, but it doesn't look right".
I like the 4X scope I have on my Marlin 30-30. It gives me great accuracy out to 100 yards, heck maybe even 150 yards.
