Sightron SIII 45x45 30mm Riflescope - Matte Finish, Dot Reticle, Side Focus, 1/10 MOA Target Knobs

The Sightron SIII 45x45 30mm riflescope is a high-magnification optic built for serious target shooters and competitive range work. At 45x magnification, it's designed to unlock fine detail at distance—ideal for benchrest, long-range precision shooting, and varmint hunting where clarity and shot placement matter. The 30mm tube diameter provides a robust platform for adjustment range and optical performance, while the fully multi-coated Zact-7 optics deliver edge-to-edge brightness even in variable light.

The side focus parallax adjustment (10 yards to infinity) keeps your target and reticle in sharp focus as you dial distance, eliminating the image shift that can plague casual optics. That precision carries through to the 1/10 MOA target knobs—resettable and tactile—which reward deliberate shooters who dial for wind and elevation rather than hold over. With 40 MOA of elevation travel and 5 MOA per revolution, you've got the adjustment range to shoot from close range out to extended distances.

At 15 inches long and 20.5 ounces, it's a full-featured scope that doesn't feel cumbersome on a dedicated target rifle. The dot reticle (0.1 mil) keeps the sight picture clean, and the matte black finish resists glare and reflection. The scope is waterproof and built to handle the rigors of the range and field without apology.

Frequently Asked Questions

What's this scope best used for?

The Sightron SIII 45x45 is purpose-built for target shooting, benchrest competitions, and precision rifle work where high magnification and fine adjustment control are essential. It's also suitable for long-range and varmint hunting applications that demand exceptional optical clarity and accurate dial-in capability.

Can I adjust for parallax at different distances?

Yes. The side focus parallax adjustment dial allows you to dial in the exact distance from 10 yards to infinity, eliminating parallax error and keeping your reticle and target in sharp focus simultaneously.

What does the 1/10 MOA click value mean?

Each click on the elevation and windage turrets adjusts your point of aim by 1/10 of a minute of angle at 100 yards. This fine resolution is ideal for precision shooting where you need to make small, deliberate corrections.
