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 1.75 5Objective Lens Diameter 32 mmEye Relief 3.5 inchesField of View 68.323.1 feet/100 yardsTube Size 1 inchTurret Style CappedAdjustment Graduation 1/4 MOATravel per Rotation 15 MOAMax Elevation Adjustment 125 MOAMax Windage Adjustment 125 MOAParallax Setting 100 yardsLength 10.2 inchesWeight 12.8 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.
