FAQ

What size scope rings does this scope need?

It has a 30mm main tube, so you need 30mm rings. A good match is the Leupold BackCountry Cross-Slot 30mm Medium Rings, or browse all scope rings.

What does second focal plane (SFP) mean?

The reticle sits behind the magnification lenses, so it stays the same size as you zoom. It stays bold and easy to see at low power, which is why most hunting scopes use it.
