I put one on my Savage FV-SR in a set of Leupold low QRW rings.
It works great, adjustments are positive and they hold (under .22LR recoil, anyhow
), and the glass is quite nice. A 50 yard zero puts the 100 yard drop right on the transition of the vertical post of the duplex reticle (using 40gr subs).
I wouldn't hesitate to recommend them.
That said, if you have a choice, use irons for Appleseed. That's part of the point.
