Vector Optics Sentinel‑X Pro 10‑40x50 SFP Riflescope – Extreme Precision for Benchrest and Long-Range Shooters

The Vector Optics Sentinel‑X Pro 10‑40x50 is a premium Second Focal Plane (SFP) riflescope purpose-built for precision shooting disciplines such as benchrest, field-target, and long-range competitions. With its impressive 10x to 40x magnification range, advanced optical design, and center-dot illuminated reticle, this scope is designed to meet the demands of expert marksmen seeking ultimate repeatability and clarity at long distances.

Unmatched Optical Performance with Fully Multi-Coated Lenses

Outfitted with a large 50 mm objective lens and fully multi-coated optics, the Sentinel-X Pro delivers outstanding brightness and sharpness throughout its entire zoom range. Even at 40x magnification, the image remains clear, making this scope ideal for daylight and indoor shooting environments where fine target definition is critical.

Purpose-Built COM‑25M Reticle for Target Precision

Designed for ultimate clarity and precision, the COM‑25M center dot reticle is tailored specifically for 25-meter benchrest shooting. The ultra-fine 1.5 mm illuminated center dot offers outstanding accuracy without cluttering the field of view. Because it's housed in the second focal plane, the reticle remains the same size at all magnification levels, ensuring a stable aiming reference.

Responsive Turret System with Zero-Stop Function

• Turret Adjustments: Precision 1/8 MOA clicks for both elevation and windage.
• Adjustment Range: Up to 50 MOA in both directions, perfect for fine-tuning your shot.
• Turret Features: Externally adjustable, lockable, and includes zero-reset and zero-stop features for fast returns to baseline settings.

Side Parallax Adjustment and Fine Focusing

The Sentinel-X Pro includes an easy-to-reach side parallax adjustment, allowing precise focus from 10 yards to infinity. This is a vital feature for competitive shooters who demand tack-sharp clarity at multiple distances without needing to reposition.

Ergonomic Comfort and Eye Protection
