ABSTRACT:
A firearm sights aligner for mounting in the bore of a firearm includes a collimator arrangement having a defuser, a sighting grid, and an objective lens. The sighting grid is mounted in the collimator arrangement so that its position can be adjusted in azimuth and elevation in response to movement of exterior mounted adjusting screw mechanisms. The adjusting screw mechanisms each include a multi-start threaded screw in order to enable full translation of the grid over its full range of azimuth and elevation in one 360.degree. revolution of each of the adjusting screw mechanisms.
