<p>A sighting gauge having a rod extending from its front edge for rotatable support on the muzzle end of the rifle barrel. The gauge has a vertically adjustable indicia bearing sighting target and is counterweighted at the bottom to hang precisely upright in a pendulum arrangement when the rod is supported in the gun barrel. A lens holder is adapted to fit on the front end of the telescope gunsight and employs a lens to bring the sighting target into focus. The lens holder may also have a transverse wall therein, removable if desired, with a peep-hole therein for more precisely aligning the telescope with the indicia on the sighting target. Furthermore, a sighting cap is adapted to be mounted on the rear of the telescope and also has a transverse wall with a peep-hole and cross hair therein providing greater accuracy for sighting in the gunsight.</p> |
