The Sightron S6 10-60x56 ED BR (MPN: 66011) is a second focal plane benchrest riflescope built on a 34 mm main tube with a 56 mm objective lens. Featuring two Extra-Low Dispersion (ED) Japanese glass elements and ZACT-7 Revcoat multi-coating, the optical system delivers 55% improved resolution over older SIII benchmarks. It uses the ExacTrack erector system to deliver fine 1/8 MOA adjustments with 55 MOA total elevation and 40 MOA windage. The optic features a side-focus parallax wheel adjustable from 9–10 yards out to infinity and is shock-rated to withstand 1,000 Gs of recoil across 10,000 cycles, accommodating spring airguns through to .50 BMG platforms.

Key Features

• ED Japanese Optics: Dual Extra-Low Dispersion lens elements paired with multi-coating maintain high contrast and edge-to-edge optical resolution at extreme magnification.
• MOA-FTD Reticle: An ultra-fine second focal plane crosshair with a central floating target dot designed to keep target scoring rings unobstructed on precision paper targets.
• ExacTrack Turret System: Exposed, zero-reset target turrets with 1/8 MOA click increments provide positive tracking across the entire adjustment envelope.
• Close-Focus Parallax Cam: Side-focus adjustment with 270 degrees of rotation focuses from 9–10 yards to infinity for rimfire and long-range use.
• Heavy Recoil & Weather Resistance: IPX7 waterproof and nitrogen-purged 34 mm aircraft aluminium chassis rated to 1,000 Gs of shock resistance.

Who is the Sightron S6 Series Bench Rest Riflescope 10-60x56mm Moa-Ftd Reticle for?

• Rimfire 25m/50m benchrest competitors — benefits from close side parallax focusing down to 9–10 yards combined with fine 1/8 MOA click adjustments to resolve and hit small rimfire scoring rings with this benchrest riflescope.
• Centerfire 100/200/300-yard benchrest and F-Class shooters — uses the upper 10x to 60x magnification envelope and dual ED glass elements to spot bullet holes on paper targets at distance without obscuring target centers via the fine MOA-FTD reticle.
• Precision stationary varmint hunters — relies on the light-gathering capacity of the 56 mm objective lens paired with a rigid 34 mm main tube to hold precise point of impact from fixed bench or prone positions.

Less suitable for: Offhand field stalking or dynamic practical disciplines like PRS; carrying a 30.5 oz (865 g), 16.8-inch optic with a high 10x minimum magnification and narrow field of view restricts rapid target acquisition, where a lighter, lower-magnification optic (such as a 3-18x or 5-25x first focal plane scope) is better suited. Targets closer than 9 yards cannot achieve sharp parallax focus.
