<p>The present invention provides a method of zeroing a weapon by sighting a graticule (11) placed in a fixed relationship to the weapon and adjusting the weapon sight such that a point on the graticule is sighted which has previously been established as a point at which the weapon is zeroed. For a rifle, the graticule is provided by a projector (21) engageable with the rifle barrel (25), the point of zeroing being predetermined by a previous sighting of the same projector after conventional zeroing. The present invention provides a method of zeroing a weapon in the field without recourse to a gunnery range, or even a firing of the weapon.</p> |
