Abstract: Weapon simulators and components for a weapon simulator are provided. In particular, a lower receiver for a weapon simulator is provided. In preferred embodiments, the lower receiver comprises a first air pressure regulator contained within the lower receiver and a second air pressure regulator contained within the lower receiver and designed to supply a higher pressure compressed air than the first air pressure regulator. The first output of the first air pressure regulator controls the second output of the second air pressure regulator. The lower receiver is designed to have the higher pressure compressed air from the second air pressure regulator drive a simulation component.

Abstract: A method for automatically predicting the cause of suboptimal shooting is provided. In some embodiments, the method comprises: providing a plurality of good example reference data to an evaluation function; providing a plurality of bad example reference data to the evaluation function; obtaining training data of a trainee's shot dispersion data; obtaining training data from at least one sensor mounted on the trainee's gun; using the evaluation function to classify the training data as good or bad; and, displaying the classification on a screen as feedback.
