Red Dot Sight

Special features of Anlong RDP-I Red Dot Sight include:
Tubeless design with 33mm reflex lens aperture provides a wide field of view, suitable
for rapid firing or shooting of moving targets besides normal shooting. 
Multi-Reticle (4patterns) or Variable Dot (4different sizes) are installed. 
Parallax corrected and unlimited eye-relief. 
Allen head screw type windage and elevation click adjustments with locking screw
(see diagram below) 
Built-in mount (integrated rail) for standard bases. No need to re-zero when remounting
the dismounted sight. 
Very light weight, waterproof and shockproof. 
Low power consumption for long battery life.

BATTERY                         
Anlong RDP-I Red Dot Sight is powered by one 3V lithium battery (CR2032 or equivalent).
Should your reticle grow dim or not light, you will need to replace the battery.
To install battery, unscrew battery cover and insert the new one + side
up, and replace the cover.

MOUNTING                       
Anlong RDP-I Red Dot Sight includes an integrated rail that fits standard, dovetailed
bases. This is suitable for most applications. Because of unlimited eye-relief
with the Anlong RDP-I Red Dot Sight, you should provide at least three inches
(7.62cm) of clearance between the end of LED and 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 with the
Anlong RDP-I Red Dot 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 Anlong RDP-I Red Dot 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 recommended. Each click adjustment moves the point of impact by 1MOA (approximately
1" at 100yds, 1/2" at 50yds).
