Just for fun, every Leupold scope is rated for air rifles, it's just that some aren't very suitable due to the parallax setting. Every Leupold rimfire scope is rated for centerfire recoil as well, but the parallax is set for 50 yards.
I swiped this of Leupolds site.
The Leupold Answer Guide
What Scopes are Recommended for Air Gun use?
All Leupold scopes will withstand the spring recoil of air guns. Leupold's EFR (Extended Focus Range) scopes will focus down to 10 meters, and out to infinity. Leupold offers two models in EFR, the 6.5-20x40 EFR and the 3-9x33 EFR. Leupold's Custom Shop also offers parallax changes to most Leupold scopes for a charge of $15.00 plus $15.00 shipping and handling. Having the parallax changed can allow the user to focus the scope down to very close distances for air gun applications.
The Leupold Answer Guide
Will the recoil of a centerfire rifle harm a rimfire scope?
Recoil of a centerfire rifle will not harm a rimfire scope. The Leupold rimfire scope is manufactured to the same durability specifications and recoil/impact tested the same as the standard scopes.
