How to use the fine tuning method of optical sight
Aim in the use of correction, there is also a problem to pay attention to, that is, in the use of fine tuning knob, because the adjustment tube is a point of fixed spring to support the return, the other two points are the high and low knob and the left and right knob, two points of force, a point of force principle. When the high and low knob is adjusted and the pressure is changed, a scattered force relative to the left and right knobs will also be generated, although it is small, but it will also affect the left and right accuracy of the light. Similarly, when adjusting the left and right knobs, there will be a relatively high and low precision effect. In particular, after the light aim is used for a period of time, the spring sheet supporting the return position will be adjusted in an unstable state due to the fatigue of the force. That is to say, after correcting the correct zero of high and low accuracy, and then correcting the left and right accuracy zero, it is found that the high and low accuracy zero is wrong, which is the reason.
In actual use, the position of the light sight holder is generally strictly controlled to minimize the adjustment amplitude of the fine tuning knob of the light sight, so as to avoid greater stress relative to another knob. Another point is to accurately grasp the zero distance of the light sighting and adjust the light sighting according to the regular needs of the actual hunting. When adjusting the light aim, the high and low and the left and right knobs should be adjusted at the same time, and the adjustment should be reversed. That is to say, if the high and low direction is to be adjusted low, then the knob should enter the wire, the left and right knob should be retreated, the number of threads should be less, and a little bit can be done. If the height is to be adjusted high, then the knob should be withdrawn, the left and right knobs should be fed, and the number of fed wires should be less! When the left and right adjustment knob, the adjustment principle of the high and low knob is the same.
