Depends upon how you'll use it and how much you want to lighten your wallet.....

A fixed 4x for a simple pinker.

A variable in the 2-12 range (2-7, 2.5-8, 3-9, 4-12, ect.) for reaching farther out on small targets.

Given the 22RF trajectory, an elevation turret for those so inclined to equate POA to POI for longer pokes.

For a factory 10-22, and not an Anschutz, the first option will likely serve well. I like Leupold glass. Used reduces price in accord. Have fun!
