Sightron SIII PLR 8-32x56 Zstop IR MOA-H Precision Long-Range Riflescope

The Sightron SIII PLR 8-32x56 Zstop IR MOA-H is a precision long-range riflescope built for shooters who demand serious glass without the premium price tag. This 8-32x magnification scope brings tactical-grade features—zero-stop turrets, illuminated reticle, and robust construction—to both competitive long-range shooters and hunters working extended distances. The 56mm objective pulls in plenty of light for low-light conditions, while the 30mm tube keeps things rigid and reliable in the field.

What sets the SIII PLR apart is its internal zero-stop mechanism: you dial in your true zero, lock it in, and get a solid tactile and audible stop every time you return to that setting. No guessing, no creep. The turrets themselves are oversized and resettable, marked clearly for windage direction, and easy to manipulate even in gloves or rough conditions. With 1/4 MOA clicks, 70 MOA of total elevation and windage travel, and 20 MOA per revolution, you've got the adjustment range and precision needed for serious distance work. The side-focus system—redesigned for a 30-yard minimum focus distance—gives you control over parallax adjustment without reaching around to the back of the scope.

The reticle is an illuminated MOA-H in the second focal plane, powered by a CR2032 battery and controlled via an 11-position side-mounted dial. Sightron's proprietary Zact-7 Revcoat Plus multi-coating maximizes light transmission for sharper, brighter images across the zoom range. The scope is fully waterproof (IPX 7 rated), fog-proof, and nitrogen-charged to handle hard use in any weather. At 15.9 inches long and 30.3 ounces, it balances well on mid-range hunting or competition builds without excessive weight.

You get a 3-inch sunshade, battery, lens covers, and adjustment tools in the box—everything you need to mount and dial it in right away.

Frequently Asked Questions

What's included in the box?

The SIII PLR comes with the scope itself, a 3-inch sunshade, a CR2032 battery for the reticle illumination, flip-up lens covers, and a Torx key and Allen wrench for turret and zero-stop adjustments.

Is this scope good for hunting and long-range competition?

Yes. The 8-32x magnification range, zero-stop mechanism, MOA-H reticle, and 70 MOA adjustment travel suit both precision hunting at distance and tactical or competitive long-range shooting. The side-focus system and rugged construction handle field conditions well.

Can I focus this scope down to short range?

The minimum focus distance is 30 yards. If you need closer focus for precision benchwork or very close range, this scope is better suited to longer-distance applications.

What does the zero-stop do?

The internal zero-stop mechanism locks in your true zero point. When you adjust the elevation turret, you get a solid tactile and audible stop each time you return to that zero—no ambiguity, no creep, and fast dial-back to known zero during long sessions.
