Monstrum G3
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.
Sightmark Core HX
The Sightmark Core HX rifle scope combines a classic red illuminated dot duplex reticle with a large 56mm objective lens, offering superior low-light performance and ensuring bright, clear images even in tough lighting. I’ve found that the red illumination greatly enhances target acquisition, allowing for fast and precise aiming in various conditions. The side focus adjustment is a game-changer, offering parallax removal without needing to shift position, which is a huge benefit for ensuring accuracy in dynamic hunting situations. The scope
