I just mounted one I picked up on the bay last week. It replaces an old Simmons Deerfield 4-12x40 scope I was using, and the improvement in the optics is stunning. Just as good optically as my 44Mag, without needing the high mounts etc. Build quality is not quite as good as the 44Mag, but I'm not complaining.

One more thing, it actually weighs in at ~15oz, not the 12oz that appears on some of the specs for them.
