    After having to re-zero my scope several times during the very rainy fall and winter hunting seasons I decided to take time to check more deeply into the problem. I removed the mount from the scope and was surprised to find corrosion around the three screws that connect the mount to the scope. It looked like an old car battery! Took a wire brush, knife blade, WD40 and a lot of elbow grease to clean it up. Put it back together using blue loctite and will go to the range today. Could the fact that the threaded inserts in the scope seem to be brass and the screws are metal be causing some chemical reaction? I would appreciate any and all input on this. I'll send an email to Pulsar today and see what they say.

    What are the chances of salt water/spray/heavy sweat coming in contact with the area of concern? I'd point in that direction first.

    I suppose I'll chalk it up to poor maintenance on my part. Pulsar replied to my email with the same conclusion.

    Ive had to rezero a couple of times as well, seems to last a month or so, before needing adjustment

    A galvanic reaction between dissimilar metals is generally triggered by salt and moisture... that's what caused me to ask my question. I suspect your initial remedy efforts will bring you favorable results in the future.
