1. A boresighting system comprising:
a laser boresight device comprising a casing configured to be loaded into a chamber of a firearm in place of a bolt carrier group, wherein the casing is configured to accept a laser device for generating a laser beam within an interior cavity of the casing, wherein the casing includes at least one keyed feature to engage with boundaries of the chamber to align an exit port in the casing to a barrel of the firearm when the casing is loaded into the chamber such that the laser beam propagates through the exit port and along the barrel; and
a parallax mitigation device comprising:
a housing for securing to at least one of a front or a rear portion of an optical sight on the firearm;
a central position indicator connected to the housing providing a visual indication of a central position of the optical sight when viewed through the optical sight;
wherein boresighting of the firearm is provided by adjusting an eye position of a user to view a laser spot on a target associated with the laser beam from the laser boresight device at a selected boresighting distance at the central position of the optical sight based on the central position indicator and adjusting the optical sight to overlap an alignment reference provided by the optical sight with the laser spot at the central position of the optical sight.
