The GPO TAC Spotter 15-45x60 (MPN: TS100) is a tactical spotting scope engineered for long-range observation, target ranging, and shot correction. Built with a magnesium alloy body and full rubber armouring, the optic combines DoubleHD glass with GPObright multi-coatings and an integrated First Focal Plane (FFP) PLR Mil-hash reticle. The straight-eyepiece chassis includes three integrated Picatinny (MIL-STD-1913) accessory rails on the top and sides for mounting red dot sights or laser rangefinders, alongside a standard 1/4"-20 tripod mounting foot and an included honeycomb killflash (ARD) objective filter cap.

Key Features

• First Focal Plane PLR Reticle: Features 0.5 mrad subtensions that scale dynamically across the entire 15–45x magnification range, allowing precise milliradian impact calls, trace observation, and range estimation without conversion math.
• Modular Accessory Mounting: Integrated top and flank Picatinny rails support co-witnessed reflex sights for rapid target acquisition or secondary electronics.
• High-Definition Optical System: Equipped with a 60 mm objective lens, DoubleHD glass, and proprietary GPObright coatings delivering a field of view of 60 m to 20 m at 1,000 m.
• Ruggedised Chassis: Sealed, nitrogen-purged waterproof and fogproof magnesium alloy housing weighing approximately 1,360 g with an eye relief of approximately 16.5 mm.

Who is the GPO TAC Spotter 15-45x60 for?

• Precision rifle competition shooters (PRS / NRL) — Delivers direct mil-to-mil shot calling and trace tracking via a First Focal Plane PLR Mil-hash reticle that maintains precise 0.5 mrad subtensions across the entire 15–45x magnification range.
• Long-range tactical spotters — Provides prone-aligned observation through a straight-eyepiece 60 mm objective tactical spotting scope weighing approximately 1,360 g, featuring integrated Picatinny rails for mounting co-witnessed target acquisition sights.

Less suitable for: Extreme-range observation beyond 1,000–1,500 m or under heavy mirage and twilight conditions where a larger 80–85 mm objective spotting scope is required; ultralight backcountry hunting where a sub-1 kg 50 mm compact optic is preferred; or upright birdwatching and shared seated viewing where an angled spotting scope is better suited.
