Abstract
Abstract A device for aligning the aiming point of a sight with the axis of a gun barrel includes a housing containing two aiming points which are capable of being made coincidental. Collimating means is focussed on one of the aiming points of the device, and image inverting and reverting optical means is focussed on the other of the aiming points. Means is provided for mounting the device on the muzzle of a gun so as to permit universal pivotal movement of the device with respect to the gun and so that the bore of the gun barrel can be viewed through the inverting reverting optical means through the gun muzzle. Once the inverting reverting optical means is centered on the axis of the gun barrel, the device is made immobile with respect to the gun, and the collimated aiming point of the device is viewed through the sight. The aiming point of the sight is then made coincidental with the collimated aiming point of the device so as to become aligned with the gun barrel axis.
