Sightron SIII SS 45x45 Competition 45x 45mm Fine Crosshair 30mm Tube SFP Riflescope

The Sightron SIII SS 45x45 Competition riflescope is purpose-built for the benchrest and F-class shooter who demands uncompromising optical clarity at extended range. This fixed-magnification optic pairs a high 45x power with a 45mm objective lens on a one-piece 30mm main tube, channeling light through ED (extra-low dispersion) glass for superior resolution, color fidelity, and contrast shot after shot.

The optic carries a precision Fine Crosshair reticle set in the second focal plane, so the crosshair maintains a constant subtension as the magnification stays locked at 45x. Resettable target turrets deliver crisp, repeatable 0.1 MOA click adjustments, while the side-focus parallax knob allows fast, precise correction from 10 yards to infinity. A factory sunshade is included to cut glare on bright days and shield the objective from damage.

Built to withstand the rigors of competition use, the SIII SS 45x45 Competition is waterproof, shockproof, and nitrogen-charged to prevent internal fogging across wide temperature swings. The scope is finished in non-reflective matte black. Overall length is 18.45 inches, with a generous 3.6 inches of eye relief and a field of view of 2.4 feet at 100 yards.
