Laser bore sighter ajuster

the device requires 2 ball bearings with a diameter of 22mm.

I decided to make this device when I noticed that my bore sighter was not correctly adjusted, indeed when you turn the device you realize that the laser is not centered.

I was inspired by a youtube video of a person who adjusts this kind of device using a lathe.

You have to adjust 4 screws at the end of the device until the laser is perfectly centered, as long as it is not centered by turning the laser draws a circle
