Bob, the best prevention to busting scopes is to tune your rifle, or have it tuned. My Sierra-Pro was a monster recoilling scope breaker. It's pretty much hit or miss whether a rifle in this class will shoot fair or harsh ( Crosman Quest varients, Gamo Shadow series guns etc). Once tuned, these rifles feel and shoot so much better than in their pure stock condition,.....Chinese mystery oils and all. You don't neccesarily have to go the full tilt custom parts tune, just build a spring compressor (as seen in the library section), order a set of lubes from Maccarri, and give it the old de-burr/lube treatment. That alone is well worth the trouble. If you have a Quest with the stamped metal trigger, then the GRT-III trigger is a must!!!! Best wishes, tjk
