Hi,
Sight is a precision instrument , users get hands after the first sight to be clear on what is moving and what is not just a twist . And its function is.
A : eyepiece diopter adjustment ring in front . Features:
Because each person shooters have different visual differences, such as some normal , some of myopia , presbyopia and some through the eyepiece diopter adjusting ring can be changed eyepiece optical path , so that the sum matches the user's eyesight .

Note : Some models of the diopter adjustment ring no internal limit device , it can not be screwed too , ranging from ring off, then re- adjust the barrel twist off and fall off.


Two : the cover of trajectory adjustment :
In addition to some of the sights outside the military , civilian sights cover to protect the majority of the internal ballistics knob , Zeroing completed, should be covered immediately to protect the interior mirror does not water or dust . Generally side , this all with an aluminum lid , and Whitworth car system , unscrew the screw carefully. Because Whitworth slippery teeth.


Three: Ballistic knob functions:
Adjust the level of the left and right bullet impact point deviation . Trajectory adjustment method : height adjustment : dial counter-clockwise twist , the point of impact will move up ; clockwise twist the dial , the point of impact to the fall ; lateral adjustment : dial counter-clockwise twist , the point of impact will be to the left ; clockwise twist dial, point of impact will be to the right ;


Four: lens group adjustment ring . Speaking lens group adjustment ring , first talk parallax
Parallax generated :
Due to the observed target and shooting targets near and far, and some may be in the 100M place , and some may be in the 1000M place , this way , targeting different distances from the target, the imaging lens group focus and distance reticle is not absolutely fixed , according to the distance from the radiation changes in the dividing lines within a certain range and objective lens focus will produce no overlap situation, when the eyes move up and down at the IPD , the crosshairs will be with eyes will move up and down and move around . This is called parallax .

Reticle and parallax relationship :
So Qiangmiao before leaving the factory , the factory will be the focus of the objective set in the most commonly used shooting distance, so the relative distance, the parallax does not exist , that does not vary with the shooter's crosshairs around the eye up and down move, but more than the factory calibrated zero outside the scope of this distance , the parallax will appear . But this time the error generated is within the allowable value . Completely negligible . Because too far away from the shot , bullets also hit, or bullet spread itself over the parallax error caused .

Specialized agencies ---- lens group adjustment ring to avoid parallax :
For some more professional shooting staff concerned, their sight more stringent requirements , in some distant range of military rifles and hunting sight , because the shooting distance situation changed greatly, engineering staff in order to improve this unfavorable situation designed lens focusing system, the front sight on the barrel twist physical distance identity, an imaging lens group and the focus is precise reticle coincide.



please test your item again, because test good before sent, if have problem still, you may :

1.) return to me exchange new or refund.

2.) keep save item, refund part $10 to you,

3.) keep save item, pay to me ship fee $40, send out new again.

is that ok?
i hope may help you resolve your problem

thanks
