Illumination combines fiber optics and self-luminous tritium, providing illumination without batteries. Tritium glows in darkness; fiber optics adjust reticle brightness in daylight. Reticle pattern supports quick target acquisition with enhanced hit probability out to 800 meters using the Bullet Drop Compensator. Windage and elevation adjustments are external; mounting bosses allow adding a Trijicon RMR. Includes thumbscrew flattop adaptor, carry-handle thumb screw, killFlash, Scopecoat, LENSPEN, lanyard for adjuster caps, Trijicon manual and warranty card.
