Overview

Experience exceptional range and accuracy with the adjustable 3-18x magnification of this high-performance tactical rifle scope, built for mid to long-distance shooting up to 1000 yards. Featuring a first focal plane MOA reticle, the etched crosshair remains proportional at all magnifications, providing clear, reliable ranging information and simplified holdover adjustments.

Constructed from durable 6061 aircraft-grade aluminum, the scope is nitrogen-charged and weather-sealed to resist fog and harsh conditions. It includes 1/4 MOA windage and elevation adjustments with zero setting, a parallax adjustment dial for sharper focus and range estimation, and red reticle illumination with multiple brightness levels for low-light visibility.

The package includes high-profile Picatinny rings, a detachable sunshade, and spring-loaded flip-up lens covers.
