Don't buy if you plan to use in the sun. I ordered 2 of these from wyvern due to his recomendation. I was going to order the leupold crossbones scopes, but Dave talked me into the hawke scopes. He said that the Hawke scopes were as good if not better than the leupolds. When the scopes showed up I was impressed with the clarity. Sighting in was quite simple. And accuracy was great. However one of the first scopes burned up on the first day shooting, the lens looked like it was covered with blisters. To Daves credit he shipped me a replacement immediately. The new scope burned up the first day I shot it. I was making an effort to keep it out of the sun. Hawke says not to expose the scope to direct sunlight or it will cause "burning effect". I have leupold scopes that I have owned for 30 years that are the same as they were new. 30 years of sun, snow, rain, mud, brush,no worries. When I'm hunting the last thing I need to worry about is sunlight. I called Dave and he offered to send me another replacement saying that the 3rd times a charm, but he advised me to call hawke customer service and they told me not to expose the scope to sunlight, but do I want to worry about not using a scope in sunlight? No. I haven't shot my new crossbow in a month because every time I look through my new 200 dollar scope I want to puke. The second Hawke scope I purchased to this date is still perfect. So Maybe I received a couple of lemons. I currently own 6 leupold scopes with zero problems. Dave from Wyvern was very helpful and the 2 excalibur crossbows and the 2 dozen bee arrows he sold me were top notch, but the hawke scopes are not.
