Not certain, but I believe Leaper's claims all their scopes are air gun rated. And even if you do break it, you can send it back with $10 for a replacement, or spend $25 and get the BSA 4x32 AO from Natchez. I'd do the latter, but then, I don't like Leapers scopes, too many problems. Don't much care how good a warranty they have, if I have to send it in for warranty work just when I need the scope the most. HTH.
