According to the principle of ballistics, any sights at close intervals, including mechanical sights, optical sights, inner red dot sights, lasers, etc., are all down, and are now beyond the schedulable plan. Normally, this interval is not within the schedulable plan.
If the impact point is always densely distributed in the normal application range, the front and rear mirror ring pad metal sheets can be used to fine-tune to correct the angle between the aiming axis and the axis of the object being used. According to the principle, only when the walking accuracy is out of range is the scope problem. If the walking accuracy is not in doubt, it is classified as no calibration or over-range adjustment. The former can be adjusted according to the adjustment and the impact point, the latter if it is too close or too far If it exceeds the scope of application, you can change the target aiming interval and select the appropriate aiming interval. If it is the asymmetry between the aiming axis and the axis of the object being used (the factory time is different from the angle between the axis of the track groove of the object being used and the vertical line They are all different. So different sighting devices may or may not be able to present this question) Just fine-tune the metal pads of the front and rear mirror rings to deal with it.
