I would be looking for a Leica ERi 3-10X50. That's the best Illuminated scope I know of.

look at the tube on that new VX5. There's hardly room to mount rings before they start the taper for the objective lense. If might work on a short action or with a picatinny rail but it won't give you much room at all to adjust for ER position without using a rail.

That Leica doesn't have daytime illumination but it is excellent in low light. I could kill a deer in a field at midnight with one.
