Sightron SIII 8-32x56 30mm Riflescope - Matte Finish, Fine Crosshair, Side Focus, 1/4 MOA Target Knobs

The Sightron SIII 8-32x56 30mm riflescope is built for shooters who demand precision without compromise. This high-magnification long-range scope combines a 30mm one-piece aircraft-aluminum tube with optical performance engineered for bench rest, prone shooting, and precision rifle competitions. The 8-32x magnification range and 56mm objective lens deliver bright, detailed images across varied light conditions, while the side focus parallax system lets you dial out parallax error on the fly—a game-changer when you're locked into position and can't move to adjust the eyepiece.

Built tough for all-weather use, this scope is nitrogen-filled, waterproof, and fogproof, so weather won't compromise your shot. The 30mm main tube is engineered with wall thickness more than twice that of standard one-inch tubes, maximizing rigidity and durability. Sightron's proprietary ExacTrack windage and elevation system delivers repeatable, precision adjustments shot after shot. The fine crosshair reticle is clean and uncluttered, ideal for precision shooting where subtension matters.

The oversized target knobs feature a quarter-minute (1/4 MOA) click value—a standard for precision rifle work—and are resettable to zero so you can dial confidently. Large protective caps shield the turrets from accidental bumps in the field. The fast-focus eyebell with diopter adjustment lets you dial your eye relief quickly without hunting for focus, and the ZACT-7 multi-coating system optimizes light transmission through seven layers of precision-ground glass.

Frequently Asked Questions

What is the side focus system and who benefits from it?

The side focus parallax adjustment lets you dial out parallax error using a turret on the side of the scope tube rather than the eyepiece. This is especially valuable in prone and bench shooting, where repositioning to access a traditional rear-mounted parallax knob isn't practical. You can adjust parallax from 40 yards to infinity without moving your cheek from the stock.

Is this scope suitable for hunting?

The Sightron SIII 8-32x56 is engineered primarily for precision rifle shooting, target work, and long-range competitions. Its high magnification range, precision turrets, and side focus system are tailored to stationary or deliberate shooting from bench or prone positions. Hunters should evaluate whether the magnification range, weight, and feature set match their specific hunting style and quarry.

How much magnification should I expect in field conditions?

The scope delivers 8x to 32x magnification depending on your selection. At 8x, the field of view is 12.2 feet at 100 yards; at maximum magnification (32x), the field of view narrows to 3.1 feet at 100 yards. The 56mm objective lens and ZACT-7 multi-coating ensure bright images across the magnification range, even in lower light.

What does the 1/4 MOA turret adjustment mean?

Each click of the windage and elevation knobs moves your point of impact by one-quarter minute of angle at 100 yards—a standard for precision shooting. The large, resettable target knobs make it easy to make repeatable adjustments, and the protective caps prevent accidental turret bumps from affecting your zero.
