Sightron
The Sightron SIII 45x45mm riflescope is a high-magnification optic built for shooters who demand precision at distance. With its 45x magnification and 45mm objective lens, this scope excels in target shooting and long-range hunting applications where a clear, magnified sight picture is essential. The 30mm tube construction provides a solid mechanical foundation, while the second focal plane design keeps the reticle size consistent across the magnification range—ideal for shooters who prefer a steady aiming point regardless of zoom level.
The fine crosshair reticle delivers the simplicity and precision that competitive and precision rifle shooters rely on. Side focus parallax adjustment lets you dial out parallax error without reaching across your rifle, keeping your cheek on the stock and your position stable. The resettable target knobs feature 1/10 MOA clicks, with 5 MOA per revolution, giving you the fine control and quick feedback that accurate shooting demands. With 40 MOA of elevation travel at 100 yards, you have the adjustment range needed for extreme-distance shooting.
Built tough for the field, the SIII is fully multicoated with Sightron's Zact-7 7-layer coating system for bright, clear glass in variable lighting. The matte black finish resists glint and corrosion, and the scope is sealed and waterproof so weather won't compromise your zero. At 15 inches long and 20.5 ounces, it balances magnification power with reasonable weight. The included sunshade helps protect the objective and cuts glare on sunny days at the range or in the field. This is a scope for shooters who understand their gear and demand reliability without compromise.

On this SIII in second focal plane (SFP) configuration, the reticle appears the same size whether you're at 1x or 45x magnification. This makes the reticle a consistent aiming reference—the crosshairs stay the same size and subtension regardless of zoom. SFP scopes are popular in target and precision shooting because they simplify holdover and wind calls.
Yes. The side focus (parallax adjustment) lets you dial parallax out from 10 yards to infinity without removing your cheek from the stock or adjusting your sight picture. This is a standard feature on high-magnification precision scopes used in target and long-range competitions.
Each click on the elevation and windage knobs moves your point of impact 1/10 of a Minute of Angle at 100 yards. One complete revolution of a knob equals 5 MOA of adjustment. This fine resolution is ideal for fine-tuning your zero and making precise wind and distance corrections at the range or for precision hunting.
The 45x magnification and 45mm objective work best on a stable shooting platform—bench rest, precision rifle setup, or a very stout hunting rifle. The high magnification is excellent for target work, long-range hunting where you can spend time aiming, and benchrest competition. Eye relief is 3.6 inches, so ensure your rifle's recoil and your mount geometry allow comfortable shooting at that distance.
