Excellent light transmission. Pinpoint accuracy in any condition. Uncompromised durability. These are the features that set the Trijicon TenmileA(R) 4.5-30x56 long-range riflescope apart. The 34mm tube provides generous elevation and windage adjuster travel. You can also expect crisp, precise adjustments with zero stop; extra-low dispersion glass for true color and detail without distortion; and dual red/green illuminated reticles that let you enjoy "both-eyes-open" shooting for fast engagement. Customize this scope with turrets tailored to your unique ballistics and environmental factors. Custom-built turrets eliminate the need to convert clicks to distance, allowing you to range the target, dial to the correct yardage, and take the shot with confidence.
