A friend asked that after the sight was installed, there was a problem with the height adjustment. The specific performance was that the height adjustment button was screwed to the limit, and the bullet was still higher or lower than the center of the aiming point. Is there something wrong with the quality of the sight?
To solve the problem, we must first find out the root of the problem. In fact, the main reason for this situation is that the axis of the sight and the gun body is different. Ideally, the optical axis of the sight should be parallel to the barrel axis. In this way, it is easy to adjust, and can play a more ideal spread
If there are problems in the installation of the sight, such as: the objective part of the mirror is too high, or the eyepiece part is too high, the relationship between the optical axis and the barrel will be as follows:
The root of this kind of installation error is the installation error of the guide rail on the gun. In addition, because the fixture is produced in different batches, there will be different heights. The solution is to use a piece of paper or a piece of copper or aluminum to place a gasket at the lower part of the front and rear fixtures to adjust the levelness of the sight,
For example, when the sight is raised, the gasket can be placed on the rear fixture (the fixture close to the eyepiece) for a little leveling.
For another example, when the collimator lowers its head, a gasket can be placed on the front clamp (the clamp close to the objective lens) for a little leveling. |
