Ohuhu Red and Green Reflex Sight with 4 Reticles Mounting: Your E/D sight includes an integrated rail that fits standard, dovetailed bases. This is suitable for most applications. Because of unlimited eye-relief with the E/D sight, you should provide at least three inches of clearance between the end ofLed & Mirror Housing and your eye when shooting. Set the rail onto the base so that the rail claw aligns with the crosscut grooves. Work the claw into the base until the cross-bolt seats into the groove. Securely tighten the locking screw with an Allen wrench included in the E/D sight. Zeroing: Select the reticle you desire by turning the reticle selector knob and set the intensity at the best position for you. With the E/D sight mounted, rest the gun on a solid support and aim at a target 50 to 100 yards (or meter) away. Test shots should be done in the same conditions to achieve maximum accuracy for adjustment, for which the use of firm rest for firing and same type cartridge is recommendable. Each click adjustment moves the point of impact by 1 MOA (approximately 1” at 100 vbs, 1/2” at 20 yards) Specification: -Weight:4.1oz/115g -Objective aperture: 33mm -Field o.V.: 15.8@ 100m -1 Click: 1moa -Length: 82mm -Package size: 4.5 x 3 x 2.8 inch Package Includes: -1 x 4 Reticles Reflex Sight -1 x Rubber lens Cap Cover -1 x Cleaning Cloth -1 x CR 2032 Battery -2 x Wrenches
