Vector Optics Sentinel-X 10-40x50 Scope Black

The Vector Optics Sentinel-X 10-40x50 Scope Black is a high-performance variable riflescope that combines power, precision and durability for serious shooters. With an impressive zoom range of 10-40x and a generous 50 mm objective lens, this scope is ideal for long-range shooting, precision training and competitive applications where magnification, brightness and accuracy are key.

Material and construction

This scope is built around a sturdy aluminium tube with a matte black finish that minimises reflections and provides protection against external damage. The optics are equipped with multi-coated lenses, which ensure a clear, high-contrast image with minimal glare, even at higher magnification settings and in difficult lighting conditions. The scope is gas-filled, which prevents internal condensation and ensures reliable performance in a variety of weather conditions. With a length of 311 mm, a 50 mm objective lens and a tube diameter of 30 mm, this scope offers an exceptional balance between light output and strength.

The reticle design (usually Mil-Dot, BDC or a precision style, depending on the model) provides a useful reference for distance estimation and compensation for wind and bullet drop at higher magnifications. Windage and elevation feature precise click settings (usually 1/4 MOA per click) to allow for precise adjustments.
