I have to say,,, the Golden Antlers that I have work extremely well and I really like them. As for the exposed adjustment knobs,,, after sighting in I always set the dials to "0",,, so when I take em out of the gun safe I give em a quick look and can tell instantly if something is wrong. You also have to periodically check the tiny allen screws (3 of em) inside the adjustment cap,,, they have a tendency to loosen up if you shoot a lot. I like the 4x32 scopes I put on my 2 QB's, but when I get the money I may order 2 more Golden Antlers and replace them as I really like the ability that a variable power scope offers when it comes to sighting in on smaller targets.
