Vector Optics Sentinel‑X Pro 10‑40x50 SFP Riflescope – Benchrest & Precision Shooterʼs Choice

The Vector Optics Sentinel‑X Pro 10‑40x50 is a high‑magnification, Second Focal Plane scope optimized for benchrest, F-Class, and precision long-range shooters. Offering a powerful 10×–40× zoom range with a premium 50 mm objective and specialized COM‑25M reticle, it delivers exceptional clarity and pinpoint accuracy—even under demanding conditions.

Optical Brilliance & 4× True Zoom

Equipped with a fully multi-coated 50 mm objective lens, it provides excellent light transmission and bright, sharp visuals across the full zoom range. At maximum magnification, you can clearly identify fine target details—essential for benchrest shooting.

Precision COM‑25M Reticle

The COM‑25M center‑dot reticle is meticulously calibrated for 25 m/yard benchrest targets at 40× magnification. As a Second Focal Plane design, reticle proportions stay constant, ensuring no distraction during magnification changes—ideal for powder-keg precision setups.

Tactical Turrets & Parallax Control

• 1/8 MOA click value on both windage and elevation turrets, with audible precision.
• Zero‑stop elevation turrets for fast return to zero after long-range adjustments.
• Side-focus/parallax dial smoothly adjusts from 10 yd to ∞, ensuring razor-sharp clarity across all engagement distances.

Robust Construction & Ergonomics

• Machined from 6061‑T6 aircraft-grade aluminum, the 30 mm tube is sealed and nitrogen-purged to resist fog, dust, and moisture.
• Rated shockproof up to .300 Win Mag, resilient under strong recoil—trusted in field-target and F-Class matches.
• Length: ~405 mm; Weight: ~790 g—balanced for bench or field use.

Illumination & Eye Comfort

Features stepless red/green illumination for the COM‑25M reticle, with smooth control to adjust brightness subtly. A fast-focus eyepiece supports diopter compensation (-2.0 to +1.5), while generous eye relief (~90 mm) makes this optic safe and comfortable for extended use.

Real‑World Feedback & Use Cases

• Highly regarded by benchrest shooters for crystal‑clear glass and affordable performance.
• Optimal for small-caliber F-Class competitors; less ideal for large calibers due to limited MOA range.
• Some users note mild edge softness at 40× and a somewhat narrow eye box—but still outstanding value for money.

Field Applications

• Benchrest & F-Class: Specialized reticle and high zoom deliver top-tier precision.
• Field‑target shooting: Clear, repeatable points of aim at 10–50 m.
• Small‑caliber long-range: Clear hole spotting and minor adjustments via 1/8 MOA clicks.
• Budget‑minded precision shooters: Professional-level features without premium price.

Technical Specifications
