Discovery Optics HS 6-24x44SFIR FFP – Precision Optics Designed for Medium and Long Range

The Discovery Optics HS 6-24x44SFIR FFP is the higher-magnification member of the HS series, built for shooters who need a reliable first focal plane optic for medium and long-range applications. The 6-24x magnification range offers genuine versatility: the lower end remains manageable for field hunting scenarios, while the upper end satisfies the demands of precision sport shooting and long-range PCP airgun use.

FFP Reticle – Accurate at Every Magnification

The engraved DLT MOA reticle on the First Focal Plane scales with the image as magnification changes, ensuring that all holdover points and windage markers read correctly at any power setting — not just at a single fixed magnification. This is particularly important at high magnification, where the accuracy of fine corrections becomes critical for consistent shot placement.

The center of the reticle is illuminated in red (center illumination), providing clear contrast against dark backgrounds, shaded targets, or during dawn and dusk conditions, without affecting the readability of the surrounding scale markings.

Side Parallax from 15 Yards

The left-side parallax adjustment wheel allows precise focus from 15 yards (approx. 13.7 m) out to infinity. This range is well suited to a 6-24x scope: the minimum parallax distance is calibrated to the magnification level, ensuring a sharp, parallax-free image across the distances where this scope is most commonly used. Useful for PCP airgunners, rimfire sport shooters, and hunters alike.

Push-Zero Lock Turrets – 1/4 MOA Click Value

The exposed turrets feature a Push-Zero Lock system: once the zero is set, the position is locked by a simple push-down action, preventing any accidental shift. The 1/4 MOA click value allows fine, repeatable corrections. The total adjustment range is 70 MOA in both elevation and windage, providing sufficient travel for medium and long-range applications in this magnification class.

Optical Quality and Mechanical Construction

The tube is machined from a single piece of aircraft-grade aluminium alloy, 30 mm in diameter and 375 mm in length. The optics use lanthanum glass with multi-layer green coating, minimising light reflection and delivering a bright, clear, high-contrast image across the full magnification range.

• OF (Objective Fixed) lens retention system — military-grade, capable of handling heavy recoil including .50 calibre
• Nitrogen-filled with quality seals — 100% waterproof and fogproof performance
• Shockproof construction — solid machined erector system for long-term mechanical stability
• Eye relief — 78–85 mm for comfortable use across different rifle platforms
• Exit pupil diameter — 7.2–1.8 mm across the 6x–24x magnification range
• Field of view — 6.4 m–1.6 m at 100 metres

Who Is This Scope For?

The Discovery Optics HS 6-24x44SFIR FFP is recommended primarily for shooters who want a capable FFP optic for medium and long-range work at an accessible price point. It is particularly well suited to hunters operating in open terrain at greater distances; sport shooters engaged in precision bench-rest or field target competition; and demanding PCP airgunners who need accurate parallax correction from 15 yards. If the magnification range of the 4-16x44 version feels limiting, this 6-24x model is the natural next step within the Discovery HS series.

What Users Are Saying

Based on international shooting and airgun forums, users of the Discovery HS series consistently praise the optical clarity and the surprisingly strong price-to-performance ratio. The lanthanum glass delivers sharp, contrasty images, and many shooters highlight that the turrets track precisely and repeatably. One user described the HS series as "a safe bet for those who don't mind a slightly larger size and weight," while others noted that "the value for money is outstanding and build quality rivals Arken-level optics." Discovery Optics has established a solid reputation in the mid- to upper-mid-range segment of affordable precision optics.
