Sightron
The Sightron SIII 6-24x50 30mm riflescope is a precision optic built for shooters who demand accuracy at distance. This mid-to-high magnification scope combines a robust 30mm tube with a side-focus parallax system and target knobs tuned for serious marksmanship—whether you're dialing steel at 500 yards or fine-tuning loads on the bench. The 6x to 24x magnification range gives you flexibility across hunting and target shooting, while the Mil-Dot reticle works intuitively for range estimation and holds that don't require custom glass.
At the heart of this scope is Sightron's ExacTrack windage and elevation system, engineered for the kind of repeatability competitive shooters and precision hunters rely on. The large, re-settable 1/4 MOA target knobs are protected by heavy caps and designed for confident adjustments in the field—no fiddling with tiny dials. The side-focus mechanism is a game-changer for prone and bench shooting, letting you dial parallax without breaking your shooting position or cheek weld. A fast-focus eyebell (with diopter range from -2.0 to +1.0) keeps your reticle sharp across varying light and shooter eye conditions.
Build quality reflects Sightron's long rifle optics heritage: the one-piece 30mm aircraft-aluminum main tube is rigid and substantial—more than twice the wall thickness of standard one-inch designs. Multi-coated ZACT-7 glass delivers excellent light transmission and edge-to-edge clarity, and the scope is sealed against the elements with nitrogen filling and fogproofing. This is an optic that handles rain, cold, and hard use without compromise.

Side focus lets you adjust parallax (image clarity at different distances) without rotating the eyepiece, which is ideal when shooting from a bench or in a prone position where breaking your position to reach the eyepiece isn't practical. The parallax adjusts from 40 yards to infinity, covering most shooting scenarios.
Yes. The Mil-Dot reticle is versatile—it allows you to estimate range using object size, hold for wind and bullet drop without dialing, and works effectively in both hunting and target shooting. The 6-24x zoom range supports both closer hunting work and extended-distance marksmanship.
Yes. The 1/4 MOA target knobs are re-settable to zero, allowing you to dial your scope to your load and then return to that zero point. They're also covered by protective caps to guard against accidental adjustment.
Sightron offers a lifetime warranty on this scope, reflecting confidence in its build quality and durability.
