The Sightron S6 10-60x56 ED Field Target Snap Focus Riflescope (MPN: 66018, SKU: SI-66018) is an optical rangefinding instrument built for competitive airgun and rimfire disciplines. Featuring a 15-lens Japanese optical system with two Extra-Low Dispersion (ED) elements and Zact-7 Revcoat Plus multi-coatings achieving 95% light transmission, it delivers high-resolution imagery across an extreme 10x to 60x magnification range. The scope is built around a heavy-duty 34 mm main tube and incorporates Sightron's Snap Focus parallax cam with DCEC (Diopter Correction & Environmental Changes) compensation, providing non-linear adjustment travel across critical mid-range distances. Designed for stationary precision shooting, the optic withstands reverse-recoil pulses and is factory shock-tested to 1,000G for 10,000 cycles.

Key Features

  • Snap Focus Parallax Cam: Non-linear side focus adjusts from 9 yards (8.2 metres) to 300 yards / infinity, providing extended cam travel across the critical 40–60 metre zone to facilitate optical target rangefinding.
  • Field Target Specific Reticle: The Second Focal Plane (SFP) MH-FT illuminated glass-etched reticle maintains a fine floating centre dot at 60x without reticle coarsening, powered by a single CR2032 3V coin cell battery with an 11-position brightness dial.
  • ExacTrack Turret System: Precision elevation and windage turrets adjust at 0.05 MRAD (0.5 cm at 100 m) per click, offering 16 MIL of total elevation travel and 11.7 MIL of windage travel.
  • Match-Compliant Indexing: The magnification collar includes an engraved 16x indexing mark to meet international competition class magnification restrictions.
  • Rugged Environmental Sealing: Rated IPX7 waterproof and nitrogen-purged for fogproof performance across varied atmospheric conditions.

Who is the Sightron S6 Series Field Target Riflescope 10-60x56mm Ed Glass Mh-Ft Reticle for?

  • Competitive Airgun Field Target Shooters — Needs extreme optical rangefinding sensitivity, which this Field Target riflescope provides via a Snap Focus cam that resolves targets from as close as 9 yd (8.2 m) up to 300 yd / infinity alongside high-definition 60x magnification.
  • Rimfire .22 LR Benchrest Competitors — Requires precise point-of-aim adjustments on small bullseyes, enabled by this riflescope's 10x to 60x magnification range, 56 mm ED objective assembly, and rigid 34 mm main tube tracking at 0.05 MRAD per click.
  • Extreme Long-Range Target Shooters — Demands high optical transmission and heavy recoil resilience, utilising this scope's 1,000G shock-rated 33.6 oz (952.5 g) chassis and 16 MIL internal elevation travel for stationary rested platforms.

Less suitable for: Target engagements inside 9 yd (8.2 m) where the parallax system cannot bring the target into optical focus, or hunters requiring an optic for mobile field stalking and strict rifle class limits such as UBR 13.5 lb ceilings; a lighter, lower-magnification optic such as a compact 2-10x or 3-9x rimfire scope is better suited to those applications.
