The value of versatility is easily found in a Trijicon AccuPower® 3-9x40mm Duplex Crosshair Rifle Scope. The magnification range and fully multi-coated optics offer an incredibly clear image with zero distortion. The Mil-Square Crosshair reticle remains constant for a more exact aiming point at higher magnifications. Green LED illumination with 11 brightness settings gives added contrast between you and the target. The "off" feature between each brightness setting saves battery life and time returning to your desired light level. The 1" hard anodized aluminum tube is lightweight and works well with bolt and AR platforms.
