Buy the Vector Optics Sentinel-X 10-40×50 Benchrest Rifle Scope in India — the most precision-engineered scope available for serious benchrest competition shooting. Designed from the ground up for 25-metre benchrest target shooting, the Sentinel-X delivers a level of accuracy and reticle precision that standard crosshair or mil-dot scopes simply cannot match.

What Makes the Sentinel-X Benchrest rifle scope 10-40×50 –  the Best Benchrest Rifle Scope in India?

Most rifle scopes are designed as general-purpose optics. The Vector Optics Sentinel-X is different — it was engineered exclusively for benchrest competition. Every specification has been optimised for the specific demands of precision target shooting at 25 metres:

• Patent Center Dot Reticle — a custom-designed reticle available nowhere else, created specifically for 25-metre benchrest target shooting
• 1.5mm Center Dot at 40x Power — at maximum magnification, the center dot is precisely 1.5mm in size, perfectly matching the 2mm diameter bull-eye on a standard benchrest target
• 10-40x Variable Magnification — dial from 10x for target acquisition to 40x for competition-grade precision aiming
• 50mm Objective Lens — large objective diameter for maximum light gathering, delivering clear and sharp images even at 40x magnification
• 30mm Monotube Body — single-tube 30mm construction provides a wider internal adjustment range compared to standard 1-inch tubes, with greater structural strength
• Turret Lock System — once zeroed, the turret lock prevents accidental adjustment during handling or transport — critical for competition shooting

Vector Optics Sentinel-X – Built for Benchrest Competition

Benchrest shooting is the most precision-demanding discipline in all of shooting sports. At 25 metres, even a 0.1mm aiming error translates to a missed bull-eye. The Sentinel-X’s patent reticle was developed after extensive testing with competitive benchrest shooters — the 1.5mm center dot is specifically sized to sit perfectly inside the 2mm bull-eye ring, giving the shooter a clear visual reference without obscuring the target.

This scope is the official choice for Indian benchrest shooters who compete with air rifles at 25 metres — including those using PCP air rifles from brands like FX Airguns, Diana, and Precihole.
