Presenting a high‑precision long‑range scope built for demanding shooters.
The Vector Optics Sentinel‑X Pro 10‑40x50 is a 30 mm tube scope providing strength and stability, while the wide 10‑40x magnification delivers exceptional detail at extended distances.
The illuminated COM‑25M reticle ensures optimal visibility in low‑light conditions, and the side focus allows crisp parallax adjustment from close to far targets with Zero Stop turrets offering fast, repeatable returns to zero.
Included accessories: High-profile Picatinny/Weaver mounts, lens caps, cleaning cloth and sunshade.
A compact, reliable, and versatile optic for tactical and precision use.

The Vector Optics Sentinel-X Pro 10-40x50 is engineered for extreme long-range precision shooting, delivering high optical performance and a robust mechanical system designed for consistent, repeatable and reliable shot execution.
The 50 mm objective lens combined with fully multi-coated optics ensures excellent light transmission, reduced chromatic aberration and sharp image clarity across the entire magnification range.
Constructed from high-strength 6063-T6 aluminum, the scope features fully multi-coated lenses that enhance contrast, reduce glare and improve target definition in demanding precision environments.
The reinforced 30 mm Nitrogen Purged monotube provides solid structural rigidity and supports a wide internal adjustment range, offering precise 0.25 MOA click values ideal for long-range shooting and fine precision corrections.
The etched SFP COM-25M Center Dot reticle is designed for precision targeting, offering a clean layout with refined subtensions and an illuminated floating center dot optimized for accurate target acquisition at any magnification.
The elevation turret includes a mechanical zero-stop (ZS) system for instant and repeatable return-to-zero, while the side-focus adjustment ranges from 25 m to infinity, supporting both close-range sight-in work and extended-distance engagements.
With generous eye relief and a precision-focused optical design, the Sentinel-X Pro 10-40x50 is ideal for shooters demanding optical quality, mechanical reliability and consistent performance in medium to extreme long-range precision applications.
Included accessories: High-profile Picatinny mounts, lens caps, cleaning cloth and a sunshade.
Precision Targeting for Long-Range Engagement
Precision-based disciplines require optics capable of delivering clarity, stability and reliable mechanical performance under demanding conditions.
Given the complexity and challenge of long-range precision shooting, scopes must excel in every aspect to meet high performance requirements.
The Sentinel-X Pro 10-40x50 provides the magnification range, optical resolution and mechanical consistency required for confident long-distance shots.

COM-25M RETICLE DESIGN FEATURES
The COM-25M Center Dot reticle is designed for practical precision shooting, offering a clean and uncluttered layout with straightforward reference marks for reliable elevation and windage control.
FLOATING ILLUMINATED CENTER DOT
A fine illuminated floating center dot provides a precise aiming reference, improving visibility in low-light conditions and supporting accurate shot placement at any magnification.
CLEAR AND SIMPLE SUBTENSIONS
The reticle features evenly spaced reference marks along the vertical and horizontal axes, allowing shooters to apply consistent holdovers and windage corrections without visual clutter.
UNOBSTRUCTED FIELD OF VIEW
The minimalist line structure maintains a wide and clear sight picture, ensuring fast target acquisition and easy tracking of moving targets.
