CZP is located at coordinates ‘I,9’ on the SAC grid (at the point of the inverted triangle). CZP is zero for the average shooter on the specified weapon platform, with a specified ammunition type, at the specified range. Adjusting weapons to CZP will almost always get shooters on paper- and very close to zero- before ever firing a shot (shooters are typically within about 2 inches of zero on a 25m target). Note that, while it is possible to have an instructor or armorer adjust weapons to CZP in order to get shooters on paper, it is best to allow the shooter to complete the process. This ensures that the shooters’ individual characteristics (i.e. height, length of pull, eye relief, etc) are properly accounted for. Results will be much better if CZP is established by the actual shooter.
Each SAC has a user specified range and ammunition type that determine relative location of CZP on the grid. This only effects establishing CZP prior to initial zeroing. Adjustments can be made by the shooter to accommodate different zero ranges. The shooter simply moves point of aim slightly higher or lower on the SAC grid.
Collimator CZP provides a significant improvement over the capability offered by existing 'boresight' products. It is more accurate than any other boresight device AND faster and easier to use than most. The improved accuracy means fewer firing iterations to achieve than when other devices are used. The speed and ease-of-use advantage makes soldiers much more likely to use the SAC- and it saves valuable training time.
While extremely useful, CZP is only a secondary or ancillary capability of the SAC. Personal Zero Position (PZP), the primary type of reference point, provides a capability that no other product is able to deliver.
