If the Rd dot is mounted fairly far forward on a bolt actions rear sights or base, what does this mean for a red dot? Or different types of red dot? Further away, more diffult to see?

I wondered about this reading in the opening query. Maybe experienced and regular red dot users can comment? Might make a difference for LRF's decision.

Maybe I'm over thinking, using a red dot on a handgun, at full arms length, the sight is reasonably far away. But not as far away as a bolt actions rear sight base.
