BLEMISHED Burris BTS 3.3-13.2x Thermal Rifle Scope USM S50 Black

The Burris BTS 3.3-13.2x Thermal Rifle Scope with 50mm objective lens (model 300600-B) is a ruggedized thermal imaging platform engineered for precision rifle work in low-light and no-light conditions. Built on Burris Company Inc.'s proven thermal optics architecture, this 4-power zoom scope delivers stadiametric ranging capability and multiple reticle options critical to accurate target engagement from extended distances. The blemished condition reflects cosmetic-only imperfections with no impact on optical or thermal performance.

Core specifications include a 3.3x to 13.2x magnification range paired with a 50mm objective lens, providing the light-gathering power and target clarity demanded in low-contrast thermal environments. Seven selectable color palettes allow operators to optimize contrast based on environmental conditions and personal preference. Hot Track technology isolates and follows moving targets, while manual and automatic non-uniformity correction (NUC) maintain image stability across temperature variations. One-handed operation via intuitive controls enables seamless adjustments during dynamic field work. The IP67 environmental rating confirms full dust sealing and temporary immersion capability—essential for harsh field deployment. Ten reticle options and adjustable contrast and brightness controls support precision shooting across varied thermal signatures and distances.

This scope serves hunters, law enforcement, and military-trained operators who require thermal targeting capability for nocturnal or low-visibility rifle work. The magnification range (3.3–13.2x) covers both close-range rapid engagement and extended precision shooting, while the 50mm objective maximizes thermal sensitivity and field of view. Stadiametric ranging integrates distance estimation into the reticle, reducing setup time and external rangefinding requirements. The combination of Hot Track, multiple color palettes, and reticle diversity addresses real-world thermal shooting demands where target contrast, ambient temperature, and distance vary unpredictably.

Thermal rifle scopes represent a distinct category within precision optics—they detect heat signatures rather than relying on ambient light, enabling target acquisition in complete darkness or through light-obscuring conditions. The Burris BTS positions itself in the mid-range thermal market, balancing magnification capability, thermal sensitivity, and operator controls without the cost premium of higher-end military-spec systems. Blemished units offer significant savings for buyers prioritizing function over cosmetic condition, making this scope accessible to serious thermal shooters and budget-conscious operators.
