I hear a lot of folks talking about the need for a 1-8x type scope. This one does that (well, it's 1.25). It has a long 6" eye relief, but it's supposed to be constant. It also has a standard plex type reticle, no illumination, and no BDC. So, I'm guessing that those missing elements are keeping it from popularity. I'd be willing to give it a go, provided the eye relief was constant throughout zoom.
