This optic utilizes Sig Sauer's advanced HDX optical system, combining Extra-Low Dispersion (ED) glass and high-transmittance lenses to deliver excellent clarity, brightness, and edge-to-edge image sharpness. The 3-18x magnification range offers optimal versatility, allowing for rapid target acquisition at low power and extreme precision at high power. Its compact footprint and lighter weight compared to larger front objective optics make it ideal for rifles where agility and reduced weight are prioritized.The BDX-T1 DEV-L MRAD reticle is a refined and feature-rich reticle designed for milliradian-based holdovers, windage, and ranging. Integrated within the sight picture is a low-profile heads-up display that presents real-time ballistic solutions calculated through the ZeroSync ballistic engine. This system receives live environmental data and range inputs from a connected KILO BDX rangefinder and updates your aiming point instantly. Shooters can engage targets without removing their eyes from the scope or making manual adjustments under pressure.Further enhancing its utility is the eTRAK elevation dial, offering precise tactile clicks and a secure multi-lock zero stop to prevent accidental changes. The scope also includes onboard environmental sensors for barometric pressure, ambient temperature, and humidity, which further refine the ballistic profile on-the-fly. Bluetooth connectivity supports seamless integration with other BDX-enabled devices within a 30-yard radius. The included ALPHA5 mount with an LRF diving board ensures a rock-solid platform and additional space for a compatible laser rangefinder, making this optic a fully integrated precision system.
