Sightron SIII PLR 8-32x56 Zstop IR MOA-H Precision Long-Range Riflescope
Sightron
The Sightron SIII PLR 8-32x56 precision long-range riflescope is built for shooters who demand accurate, repeatable adjustments at distance without the premium price tag. This second focal plane scope combines a robust 30mm tube with true zero-stop technology, tactical-style resettable knobs, and an illuminated MOA-2 IR reticle—everything you need to dial in on target from the bench or in the field. Whether you're dialing for competitive long-range shooting or hunting at extended ranges, the SIII PLR delivers the adjustment range and optical clarity to perform.
Sightron engineered this scope around the shooter's workflow. The new internal zero-stop mechanism locks your elevation at true zero with positive tactile and audible feedback—no more uncertainty when you reset after a day's shooting. The windage knob is clearly labeled left and right, eliminating guesswork in adjusting for wind. Oversized tactical turrets are easy to grip and manipulate even in heavy gloves or cold weather. With 70 MOA of travel in both windage and elevation, and 20 MOA per knob revolution, you get fine precision and the adjustment range serious long-range work demands.
Optically, the PLR series uses Sightron's Zact-7 Revcoat Plus multi-coating system to maximize light transmission and clarity across the 8–32x magnification range. The side-focus system is redesigned for improved close focus, down to 30 yards. The illuminated reticle runs on a standard CR2032 battery and features an 11-position dial for quick on/off and brightness control. The scope ships fully sealed with nitrogen and rated IPX 7 waterproof, so rain, splash, and fog won't compromise your optics. A 3-inch sunshade, lens caps, and adjustment tools round out the package.
At 30.3 ounces and 15.9 inches long on a 56mm objective, the SIII PLR balances performance and handling. This is long-range glass for hunters and shooters who want a proven platform without paying for brand markup.
