BUIS Through Variable Scope?

needs more ammo
The lowest power scopes I have are 1.4x and 1.5x.
If I take a photo of the scope reticle, the front sight is 75% in focus. However, if I look through the scope with either eye the front sight is maybe 20% in focus at best. Which means you can hardly make out the front blade and its more of a ghost image than something you can precisely use.
It would seem the very nature of a scope means that the close up focus range is far forward of where a rifle front sight is located.
I wonder if 1x telescopes are the same. Perhaps someone with a 1x prism red dot could lend their experience as well.

The first problem I see is that there is most likely no way to mount your scope at the proper location for correct eye-relief and still have your rear BUIS raised up so you can sight thought it.
A true 1" red dot optic like an AimPoint PRO or similar can be mounted close up to your eye, or far enough forward to have your sight up behind it, but a scope with any level of magnification is going to need to be positioned close enough to your eye that you get your full field of vision through the scope. (I.e. avoiding the black "doughnut" that comes from having the scope too far away from your eye.)

Its not viable, that is why they make QD mounts so you can quickly lose a broken scope and flip up the BUIS, and why they make 45 degree offset BUIS so you can quickly tilt the gun for close up iron sight work without changing your grip to futz with a zoom ring.
Depends on your need for the BUIS. Most of mine are the former so I don't totally lose an outing if a scope goes south (I have lots of guns, but relatively few "high end" scopes that "shouldn't break", when I buy optics I mostly spend my money on camera gear). I've played with the later and it works well but adds two more things to "snag". Lately I've not been worrying much about having BUIS as my eyesight has made using them little better than "I fart in your general direction".
