The Sightron SIII 10-50x60 riflescope is a high-magnification optic built for shooters who demand precision across extreme distances. With a 30mm tube and variable magnification running from 10x to 50x, this scope handles everything from mid-range hunting to serious long-range target work. The side-focus parallax adjustment lets you dial in the precise distance to your target, eliminating parallax error and sharpening your sight picture from 13 yards all the way to infinity.
The MOA-H reticle is calibrated at 24x magnification and works in concert with the 1/8 MOA tactical knobs, giving you fine control for dialing corrections and holdovers on distant targets. Those resettable knobs are built for serious shooters who zero and reset to baseline, then work with the reticle for wind and elevation adjustments. The 30mm main tube provides plenty of internal adjustment range—50 MOA of elevation travel at 100 yards—so you can dial hits without running out of mechanical correction.
Built tough for the field, the scope features fully multi-coated Zact-7™ 7-layer lens coatings to maximize light transmission and image clarity, even in challenging light. The matte finish resists glint and blends into most rifle setups. At 30.1 ounces and 16.9 inches long, it strikes a balance between optical capability and practical weight. The scope is fully waterproof, so weather won't compromise your zero or reliability. Lens covers are included; a sunshade is not.
This is a scope for hunters and shooters serious about precision, whether you're working steel at distance or pursuing game across varied terrain where your shot might come from anywhere from 100 to 600+ yards.

The click value refers to how much your point of aim moves with each turn of the knob. The 1/8 MOA knobs on this scope mean each click adjusts your aim by 1/8 inch at 100 yards, allowing finer precision than the coarser 1/4 MOA standard. This fine control is especially valuable at high magnification and for long-range shooting where every small adjustment counts.
The Sightron SIII 10-50x60 is equally at home in both disciplines. The low end of the magnification range (10x) keeps your field of view wide enough for hunting in variable terrain, while the extreme 50x magnification makes it excellent for precision target work and long-range validation. The side-focus parallax adjustment and tactical knobs appeal to precision shooters, but the overall design works for any application demanding serious optical capability.
Yes. The MOA-H reticle includes hash marks and holds that let you estimate wind and elevation correction and aim off the center of the reticle—a technique called "holdover." You dial corrections only when you want to reset your zero or make precise mechanical adjustments. Many shooters use both methods depending on their situation.
Side focus means the parallax adjustment knob is located on the side of the scope body rather than on the eyepiece. You dial in the distance to your target to eliminate parallax error—the apparent shift in reticle position relative to the target when you move your head slightly. This scope adjusts from 13 yards to infinity, covering the vast majority of shooting scenarios.
