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 first focal plane (FFP) mean?

The reticle sits in front of the magnification lenses, so it grows and shrinks as you zoom. That keeps every hash mark’s value the same at any power, which makes holdovers and ranging work at any magnification.
