Doowroh, not that it matters as you’ve solved the issue for yourself, but I think you have it backwards, front sights operate opposite of rear sights. So, if the front sight was too low your point of impact would be too high. If you did want to try to remedy the iron sight issue you could try to file down the front sight post, this will move your point of impact up, enabling you to use the irons for further out.
Now, to the scout scope question. I have the vortex 2-7 on one scout and the weaver 4x on another. Before I get jumped all over for having two scouts, I will say it isn’t my first choice for an optic mounting system, sometimes you have to work with what you have. Between the two styles of scopes (fixed vs variable) I would say it’ll come down to weight / bulk and how you want to shoot it. The weaver is much lighter and more compact, but at 4x and with a fairly thin reticle it is more difficult to shoot with both eyes open. The vortex set on 2.5-2.75 is amazing for shooting with both eyes open, and the option of cranking it up to 7x is always nice, but it is a heavier and bulkier design.
Happy scope hunting
