Vector Optics Sentinel 10-40x50 Second Focal Plane – 1/8MOA, 11-Level Illumination, 25m Benchrest

Overview for benchrest shooters

The Vector Optics Sentinel 10-40x50 is a purpose-built scope crafted for 25-meter benchrest airgun competition. Its design emphasizes precise aiming, repeatable adjustments, and reliable performance in varied lighting. With a fast-focus eyepiece for easy diopter tuning, the scope helps you dial in sharp focus quickly and maintain crisp reticle visibility across sessions.

What makes it sit up to the task

• Optimized optics for 25 m benchrest shooting, including a reticle that aligns with a 2 mm target diameter when magnified to 40x power.
• Diopter compensation from -2 to +1.5 through a fast-focus eyepiece, helping you customize sharpness for your vision without strain.

Illumination and reticle

Shine through variable light with an upgraded 11-level illuminated center dot reticle. The illumination supports clear targeting from dim indoor ranges to brighter outdoor days, aiding consistent aiming without overwhelming the sight picture.

• 11-level illumination provides flexibility for different lighting scenarios.
• Center-dot reticle design promotes quick target acquisition at higher magnifications.

Precision, tuning, and zeroing

The Sentinel pairs precise optics with robust mechanical tuning. A 50 mm multi-coated objective lens delivers bright, edge-to-edge clarity, while the elevation and windage offer generous travel and fine-tuning through 1/8 MOA increments. With 50 MOA of elevation and windage and 100 clicks per full rotation, you have ample room to dial in ballistic conditions to your bench setup.

• 1/8 MOA click adjustments for incremental precision during target sessions.
• 50 MOA elevation and windage with 100 total clicks per rotation for fine alignment.

Zero Stop, durability, and build

The Zero Stop system gives you a reliable return-to-zero reference, smoothing repeatable setups across sessions. The body is built from 6061-T6 aluminum and is shock-tested to 750G with IPX4 water resistance, ready for field use and transport between ranges.

• Zero Stop enables quick, repeatable zero returns after dialing elevation or windage.
• Rugged 6061-T6 aluminum chassis with IPX4 protection resists moisture and routine handling wear.

What you get in the box

Included accessories support setup and maintenance: a user manual, plastic wrench, cleaning cloth, flip-up caps, hex keys, and a sunshade, ensuring you can get to the bench quickly and keep the optics protected between sessions.

• User manual and essential maintenance tools for onboard upkeep.
• Flip-up caps and sunshade to shield lenses from dust and sunlight.

Note: Performance claims depend on setup, technique, and shooting conditions. This scope offers features and capabilities that may improve aiming accuracy and consistency when used as part of a suitable benchrest setup.
