Red Dot Sight Description

RDP-IV AUTO BRIGHTNESS RED DOT SIGHT This tubeless design reflex lens aperture provides a wide field of view. Suitable for rapid-firing or shooting of moving targets besides normal shooting. Automatic red dot brightness adjustment offers the integrated control circuit adjusts the brightness of the aiming dot to varying light levels in the surroundings. The brightness sensor on the front side of the sight senses the brightness in target direction. When the target surroundings are dark, the red dot will be dimmer. When target surroundings are bright, the red dot will be brighter. The red dot is firmly factory-adjusted parallax-free to 40 yards. This adjustment ensures the parallax-related aiming errors are minimized over a large distance range. This red dot does not contain a separate ON/OF switch. When the red dot sight is covered, it is in the power-saving mode (off ). When the cover is removed, the red dot is turned on automatically. INSTALLING BATTERY: RDP-IV Tubeless Sight is powered by one 3V lithium battery ( CR2032 or equivalent). When your reticle grows dim or darker, you will need to replace the battery. The battery can be replaced without removing the RDP-IV. Simply pull the battery compartment using your fingernail (or small tool) and remove the battery. Place a new battery (+side up ) on the battery compartment and push it back as it was until you can hear a click sound. The RDP-IV does not require re-zeroing after replacement of the battery, whereas other sights need to be removed, re-zeroed, and remounted. MOUNTING: RDP-IV sight includes an integrated rail that fits standard and dovetailed bases. This is suitable for most of the application. Because of the unlimited eye-relief with the sight, you should keep at least three inches of clearance between the end of the sight 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 the supplied allen wrench. WINDAGE AND ELEVATION ADJUSTMENT: Before you make any adjustment, make sure using the Allen key(provided in package ) loosing two locking screw to void damage of merchandise.
