Vortex Crossfire II 3-9x40 Riflescope

This riflescope delivers variable 3-9x magnification through a 40 mm objective lens. It is built for shooters who need a clear, durable optic for mid-range hunting or target work. The Dead-Hold BDC MOA reticle assists with holdover estimation. The single-piece aircraft-grade aluminium tube is nitrogen purged and o-ring sealed for waterproof and fogproof performance.

Second Focal Plane Reticle Behaviour

The reticle sits in the second focal plane, so its subtensions remain visually constant across the magnification range. Accurate holdover using the Dead-Hold BDC MOA markings is only valid at the highest 9x setting. At lower powers the spacing no longer matches the calibrated MOA values, limiting precise ranging to one magnification.

34.1-12.6 Feet Field of View at 100 Yards

The field of view spans 34.1 feet at 3x and narrows to 12.6 feet at 9x measured at 100 yards. This figure defines how much scenery you see through the optic and determines whether the scope suits your typical engagement distances. Buyers who need a wider view at high magnification should consider a different optical design.

Questions about this item

Should I pick the 3-9x40 model or a different magnification range?

The 3-9x40 gives a 34.1-12.6 feet field of view at 100 yards, so choose it when you want variable zoom with a 40 mm objective for low-light brightness.

What does the 3-9x magnification actually deliver on target?

It lets you zoom from three to nine power, shrinking the field from 34.1 to 12.6 feet at 100 yards while the 40 mm objective gathers light for a bright image.

How does the 1-inch main tube and MOA reticle work together in practice?

The 1-inch tube holds the Dead-Hold BDC MOA reticle in the second focal plane, so subtensions stay correct only at the highest 9x setting for hold-over ranging.
