The Sightron SV Series 10-50x60 ED Riflescope (Model 27008) is a high-magnification optic engineered for extreme-distance target disciplines. Built around a 34 mm main tube machined from aircraft aluminum, it pairs Extra-Low Dispersion (ED) Japanese glass with Sightron's proprietary Zact-7 Revcoat 7-layer anti-reflective coatings to reduce chromatic aberration. The optical design integrates the patented F.A.S.T. (Fine Adjustment Sight Tuner) coaxial dual-dial side-focus system, which combines a standard coarse parallax adjustment with a 4:1 geared micro-focus dial for refined target focus from 10 yards to infinity. Elevation and windage adjustments feature the ExacTrack erector mechanism to maintain consistent tracking pressure across the travel range, driven by target-style push/pull locking knobs delivering 1/8 MOA click values.

Key Features

• High-Magnification Optical Assembly: Features a 10x to 50x magnification range and a 60 mm objective lens for enhanced detail resolution at long ranges.
• Target Dot .1 Reticle: Etched glass, non-illuminated second focal plane reticle providing a 0.1 MOA center dot at 50x magnification (0.5 MOA at 10x) with ultra-fine crosshairs to minimize target subtension.
• Dual-Dial Parallax Focus: Coaxial side-focus assembly with a 4:1 geared fine adjustment wheel focusing from 10 yards (9.1 m) to infinity.
• Precision Erector System: Patented ExacTrack erector assembly delivers 1/8 MOA per click adjustments with 10 MOA per full revolution.
• Weatherproof Construction: Nitrogen-purged, fogproof, and certified waterproof under the IPX7 standard for submersion up to 1 metre for 30 minutes.

Who is the Sightron SV Series 10-50x60 ED Riflescope for?

• F-Class competitive shooters — Requires the 10x to 50x magnification range and 1/8 MOA turret adjustments to resolve distant target rings and apply precise point-of-impact corrections without obscuring the bullseye using this precision riflescope's fine reticle.
• 1,000-yard benchrest competitors — Relies on the 60 mm objective lens coupled with ED glass and the 34 mm tube platform to maintain resolution and tracking repeatability across 70 MOA of internal elevation travel.
• Rimfire silhouette and precision air rifle competitors — Benefits from the close-focus capability that dials down to 10 yards combined with 1/8 MOA clicks for millimeter-level shot placement on small targets.

Less suitable for: Mobile stalk-hunting or handheld walk-around shooting due to the 42.7 oz (1.21 kg) weight and narrow 2.2-foot field of view at maximum magnification, where lightweight field optics under 700 g are preferred. It is also less suitable for extreme-range shooting without an inclined 20 to 40 MOA base, as the 70 MOA total elevation travel will run out of upward adjustment.
