The Hikmicro Stellar SX75LR 4.0 is a flagship thermal rifle scope engineered for extreme-range observation, targeting, and ballistic calculation in open environments. Built around a 1280 × 1024 uncooled focal plane array with a 12 μm pixel pitch and an industry-leading thermal sensitivity of less than 12 mK, it resolves minute temperature differentials even in challenging atmospheric conditions. Featuring a 75 mm F1.2 objective lens delivering a 3× base optical magnification and up to 30× total magnification, the optic projects imagery onto a 1.03-inch AMOLED display operating at 2560 × 2560 resolution. The system integrates an internal 1,200 m laser rangefinder concealed directly behind the objective lens, feeding real-time target distance into an on-board ballistic calculator.

Key Features

• Internal Laser Rangefinder: Concealed in-lens LRF measures distances from 10 m to 1,200 m with ±1 m accuracy, linking directly to the embedded ballistic calculator.
• Extreme Thermal Resolution: Combines a 1280 × 1024 sensor with sub-12 mK NETD sensitivity and Image Pro 4.0 processing for high-fidelity anatomical identification.
• Recoil-Rated Performance: Shock-resistant up to 6,000 J, providing structural integrity for magnum hunting calibres including .300 Win Mag and .338 Lapua.
• Zeiss Rail Mounting: Features an integrated mounting rail interface (Zeiss rail/saddle profile) for secure alignment on compatible rifle platforms.
• Dual Power Architecture: Powered by internal rechargeable cells alongside a replaceable 18650 Li-ion battery, charged via 5V USB-C or the included dual-slot external charger.
• Shutterless Imaging: Utilises the HIKMICRO Shutterless Image System (HSIS) to maintain an uninterrupted visual feed without periodic shutter freeze.

Who is the Hikmicro Stellar SX75LR 4.0 for?

• Professional feral pest controllers targeting pigs and wild dogs across open Australian plains — requires the 1280 × 1024 sensor resolution paired with the integrated 1,200 m laser rangefinder to confirm pest identity and calculate immediate ballistic firing solutions at extreme field distances using this thermal rifle scope.
• Long-range hunters requiring precise trophy appraisal and anatomical placement — relies on the 75 mm lens offering 3× optical magnification and < 12 mK sensitivity to resolve fine anatomical details and bullet placement boundaries on distant game targets.

Less suitable for: Hunters operating in tight bush or dense scrub at distances under 30–50 m, who are better served by a wide-field thermal scope featuring a smaller 35 mm or 50 mm focal length; and active, long-distance stalk-and-carry hunters, who are better served by lighter sub-900 g thermal rifle scopes rather than this 1,140 g platform.
