You won't like my opinion of RWS scopes. I bought a RWS 450 3-9X40 a couple of years ago. I am now on my second REPLACEMENT of that scope! :shock: The REPLACEMENT will have to be replaced becaused the ocular is stuck and can't be focused! Considering the PRICE paid for that scope, it should be a good one. It isn't. DEFINITELY one of the air gun items to be avoided. You couldn't give me one. DNR has the RWS 300 scope you are considering for $121.17. A MUCH better choice would be the Swift 4-12X40AO 676/676M for $117/$120 from eabco.com. I have six or seven or so of these scopes and there isn't a better air rifle scope for the money. Another excellent scope would be the Bushnell Trophy 4-12X40 73-4124, $151.80 at dnrsports.
BTW, that Stingray is a really nice air rifle!
