The Sightron S6 ED SFP 10-60x56 IR MH-FTSF Riflescope is Sightron's purpose-built precision riflescope engineered for the most demanding airgun, .22 caliber field target, and benchrest competition shooters, representing the pinnacle of the S6 platform with a 10-60x magnification range that gives competitors unprecedented resolution and target detail at extreme ranges. The scope is built around a 15-lens optical system using Japanese optical-grade glass with two strategically positioned Extra-Low Dispersion elements that deliver a claimed 55% improvement in optical resolution over the award-winning SIII platform, paired with Sightron's Zact-7 Revcoat Plus fully multi-coated lens system for maximum light transmission, contrast, and chromatic aberration reduction. The redesigned parallax cam system offers 330 degrees of total travel — with 291 degrees dedicated to precise field target parallax adjustment from 9 yards to 300 yards and an additional 39 degrees reserved to compensate for diopter correction and environmental changes that affect target-ranging accuracy. Constructed from premium-grade aluminum in a 34mm tube, the scope weighs 33.6 oz, is rated to 1,000G shockproof for over 10,000 cycles from heavy airgun recoil up to .50 BMG, and is nitrogen-purged and IPX7 waterproof certified, backed by Sightron's Lifetime Performance Guarantee.
