Go from clanging steel at 600 yards to knocking down a big game prize with the Trijicon® AccuPower® 4-16x50mm Mil Square Crosshair Rifle Scope. The magnification range and fully multi-coated optics offer an incredibly clear image with zero distortion. The Mil-Square reticle was designed by a former Marine sniper to provide additional target information for increased accuracy. Green LED illumination provides added contrast to incorporate the "two-eyes open" Bindon Aiming Concept. 11 brightness settings with "off" feature between each setting saves battery life and time returning to your desired light level. The 30mm hard anodized aluminum tube is lightweight and can be mounted using rings or quick release mount.
