Sightron SIII 8-32x56mm Riflescope, 30mm Tube, MOA-2 Reticle, Side Focus, 1/4 MOA Adjustments, Zero Stop, Matte Finish

The Sightron SIII 8-32x56mm riflescope is a versatile optic built for shooters who need flexibility across multiple distances and shooting scenarios. With its 8–32x magnification range and 56mm objective lens, this scope delivers bright, clear images whether you're dialing in at 100 yards or stretching shots to steel at extended range. The 30mm tube provides robust elevation and windage adjustment travel—70 MOA of vertical room—giving you plenty of correction for long-range hunting and competitive shooting without running out of dial.

Built with Sightron's Zact-7 seven-layer multi-coated optics, the SIII renders a sharp, high-contrast sight picture in varied light. Side focus allows quick parallax correction without breaking your cheek weld, and the MOA-2 reticle at 24x magnification pairs clean aiming with a usable target subtension. Quarter-minute (1/4 MOA) click adjustments let you dial precise corrections, while the tactical (resettable) knobs and zero stop function mean you can return to your zero point confidently—critical if you need to spin the elevation turret and come back. The matte black finish resists glint and blends into any rifle.

At 26.5 ounces and 15.35 inches long, this scope balances optical quality with practical weight and balance on hunting and tactical rifles. Fully waterproof construction keeps the optics safe in weather, and Sightron includes a sunshade to reduce flare and protect the objective lens in the field.

Frequently Asked Questions

What rifle magnification and distance range is this scope built for?

The 8–32x magnification range makes the SIII flexible across hunting and target-shooting distances. The lower end (8x) keeps your field of view wide enough for closer work and running targets, while the 32x magnification suits long-range precision shooting and glass-heavy hunting scenarios. The 70 MOA of elevation travel supports high-velocity and mid-range cartridges without running out of dial on extended shots.

Does this scope need to be installed on 30mm rings, or can I use 1-inch rings?

This scope uses a 30mm tube, so you must use 30mm scope rings to mount it. The larger tube provides the elevation travel and structural rigidity needed for the 70 MOA adjustment range.

What's included in the box?

The Sightron SIII comes with a sunshade. You will need to purchase scope rings and bases separately to mount it on your rifle.

Can I use this scope in rain or wet conditions?

Yes. The SIII is fully waterproof and sealed, so it will perform reliably in rain and wet field conditions without fogging or water intrusion.
