The Sightron S6 5-30x56 ED Zero Stop (catalogued in Australia under the legacy series name Sightron SVI Series 5-30x56mm Riflescope) is a long-range precision riflescope engineered for extreme accuracy on stationary platforms. Built around a 34 mm single-piece aircraft-grade aluminium tube, it incorporates Japanese Extra-Low Dispersion (ED) glass treated with proprietary Zact-7 Revcoat Plus fully multi-coated surfaces to optimise light transmission through a large 56 mm objective lens. For reliable dialling, the scope integrates Sightron's ExacTrack windage and elevation system with an internal mechanical Zero Stop, paired with an illuminated, glass-etched MOA-7 Second Focal Plane reticle powered by an 11-position intensity dial.

Key Features

• Japanese ED Optical System: Integrates Extra-Low Dispersion glass elements with Zact-7 Revcoat Plus multi-coatings to reduce chromatic aberration and enhance edge-to-edge target clarity across the 5x to 30x magnification range.
• ExacTrack Mechanical System: Employs a patented erector tube assembly that maintains constant alignment pressure to prevent tracking drift across 80 MOA total elevation and 60 MOA total windage travel.
• Tactical Turrets with Zero Stop: Features exposed turrets with 1/4 MOA click values, 20 MOA per revolution, and a mechanical Zero Stop for an audible and tactile return to zero.
• Close-Focus Parallax Adjustment: The side focus dial adjusts parallax from 10 yards (9.14 m) out to infinity, supporting both short-range rimfire applications and extreme long-range centrefire shooting past 1,000 metres.
• Recoil and Environmental Sealing: Rated to withstand 1,000 G recoil shock for standard and magnum calibres, sealed to an IPX7 waterproof standard (1 m submersion for 30 minutes), and nitrogen gas-purged against internal fogging.
• Standard Australian Power Availability: The glass-etched reticle runs on a single standard CR2032 3V lithium coin-cell battery.

Who is the Sightron Svi Series 5-30x56mm Riflescope With Second Focal, Ed Glass, Zero Stop, Illuminated Moa-7 Reticle, 34mm Tube for?

• F-Class and benchrest target shooters — Delivers up to 30x magnification alongside a fine Second Focal Plane reticle that does not expand over distant bullseyes, supported by a 34 mm tube providing 80 MOA of internal elevation travel.
• Varmint hunters shooting from static positions — Combines a 56 mm objective lens for low-light clarity with a side focus dial capable of eliminating parallax down to 10 yards (9.14 m) for small vermin at short, intermediate, and long distances.
• Long-range static hunters — Provides a 1,000 G shock rating to withstand heavy magnum rifle recoil, supported by a mechanical Zero Stop for quick returns to base zero after dialling out past 1,000 metres.

Less suitable for: Shooters requiring active stalking or backcountry carry will find a lighter, more compact 1-inch or 30 mm hunting scope better suited than this 33.3 oz (944 g) optic, while dynamic field PRS or NRL competitors needing accurate holdovers across variable powers will prefer a First Focal Plane (FFP) scope.
