The system would determine the line of bore based on the SAMMI dimension of the chamber. The camber insert, through AI and ML, would learn how far it is off-center and compensate for the variation, using the true center of the bore. It does not need a laser; the laser method is outdated. It has reached its maturity in the product life cycle; you can't make it any better, greener, redder, bigger, or smaller, not better. Another sensor that attaches to the scope determines the line of sight and knows the diameter of the scope tube, as well as the location of the crosshairs, based on the scope's make and model. At this point, the line of sight and the line of bore are running parallel. The app determines the actual scope height from the line of sight to the line of bore. Give the app your distance to the target, and it can display the intersection of the line of sight on the line of bore by showing a dot on the app's screen on your phone. The attachment to the scope displays your crosshairs, and now you can move them with the turrets to the intersecting point shown on the phone's display as a dot.
