Diamondback riflescopes are loaded with features. First, the solid one-piece aircraft-grade aluminum alloy construction makes the Diamondback riflescope virtually indestructible and highly resistant to magnum recoil. Argon purging puts waterproof and fogproof performance on the agenda, and advanced fully multi-coated optics raise an eyebrow when crystal clear, tack-sharp images appear in the crosshairs. Look for all this and more in a riflescope you’d expect to cost quite a bit more, but doesn’t.SpecificationsMagnification 3.5 10Objective Lens Diameter 50 mmEye Relief 3.3 inchesField of View 35.813.5 feet/100 yardsTube Size 1 inchTurret Style CappedAdjustment Graduation 1/4 MOATravel per Rotation 15 MOAMax Elevation Adjustment 65 MOAMax Windage Adjustment 65 MOAParallax Setting 100 yardsLength 12.5 inchesWeight 16.2 ouncesOptical FeaturesFully Multi-Coated Increases light transmission with multiple anti-reflective coatings on all air-to-glass surfaces.Second Focal Plane Reticle Scale of reticle maintains the same ideally-sized appearance.
