Discoveryopt® MS 3–9×40 SFP MOA Riflescope

The Discoveryopt MS 3–9×40 SFP MOA combines a 3–9× magnification range, 40 mm objective lens, and a reticle in the second focal plane. Its MOA-based elevation and windage adjustments provide a 0.25 MOA click value and 70 MOA of total travel. The riflescope also features fixed parallax at 100 yd, a 1 in / 25.4 mm main tube, nitrogen-purged construction, and an IP66 rating.

3–9× Magnification Range

The 3–9× magnification range provides a wider field of view at the lower settings and supports more precise aiming at increased distances when higher magnification is selected. The field of view ranges from approximately 14.5 to 4.9 m at 100 m. The exit pupil ranges from 13.1 to 4.3 mm, while eye relief measures approximately 83 to 72 mm.

Second Focal Plane Reticle and 0.25 MOA Adjustments

The reticle is located in the second focal plane, meaning its apparent size remains constant as magnification changes. Each elevation and windage click equals 0.25 MOA, corresponding to approximately 7.3 mm at 100 m. The riflescope provides 70 MOA of total elevation travel and 70 MOA of total windage travel.

Fixed Parallax and Locking Diopter

Parallax is factory-set at 100 yd, or approximately 91.4 m, and there is no user-adjustable parallax control. The diopter can be adjusted to the shooter's eyesight and locked to help prevent unintended changes.

One-Inch Main Tube and IP66 Protection

The riflescope features a 1 in / 25.4 mm main tube, measures 307 mm in overall length, and weighs 350 g. Nitrogen purging helps prevent internal fogging, while the IP66 rating provides dust-tight protection and resistance to powerful water jets. The manufacturer rates this model for use on spring-piston air rifles and firearms chambered in .223 Rem or 5.56 NATO.

Package Contents

The package includes the riflescope, lens covers, cleaning cloth, user manual, 2 specification cards, warranty card, and inspection card. Scope rings are not included and must be selected separately for the 1 in / 25.4 mm main tube.
