I'm getting ready to order the RS mount for a micro dot, I know the 301 is recommended, what about the 303 mount?

I didn't know how the eye relief was coming from the vicinity of the rear irons, or if I'd like to have the advantage of the full 303 rail to move even more rear.

I've run the dot on the Ultimak, I just don't like the eye relief so far forward, which is why I'm going to try the RS product.

Opinions?  Comments?

It's all personal preference
