FIELD OF THE INVENTIONThe present invention relates to sighting systems for firearms, and more particularly to mechanisms for adjusting sighting systems.
BACKGROUND OF THE INVENTIONMany current sighting systems may be challenging to configure to a firearm. To be effective, at least some aspect of a sighting system requires strict alignment to the barrel of the firearm or to the ballistic trajectory of projectiles emitted from the barrel. In many current sighting systems, a unique zero for the firearm is stored in the sighting system. The unique zero typically includes adjustments for windage and/or elevation. These adjustments are typically made through adjustment mechanisms for windage and/or elevation on the sighting system. The unique zero is often a result of variation in firearm design, a range of manufacturing tolerances for component dimensions, and the assembly of firearm components. Therefore, many current sighting systems are calibrated for the unique zero of only one firearm at a time. Replacing the sighting system would require making adjustments to the windage and/or elevation on the replacement sighting system to match the unique zero of the firearm. Moving the sighting system to a second firearm would require making adjustments to the windage and/or elevation on the sighting system for the unique zero of the second firearm. The time and effort required to make adjustments for windage and/or elevation in many current sighting systems is significant enough that users of firearms often utilize a sighting system for each firearm. What is needed is a sight adjustment facility.
