The small arms collimator (SAC) is a very precise, advanced optical device that allows shooters to check zero and/ or re-zero weapons in just a few seconds in any environment— without live fire. By ensuring that weapon, sight system, and shooter are always properly tuned to each other (properly zeroed) the SAC helps maximize the capabilities of each. It can also be used to speed up the initial zero process, as a training aid when teaching marksmanship fundamentals, and to help quickly diagnose problems with weapons, sights, or mounts.

Why Use the SAC?

…..
In combat, the difference between an enemy that is down and out of the fight versus one who is able to continue to send rounds in your direction is often measured in inches. For this reason, we should constantly strive to improve combat marksmanship. The SAC is a very powerful tool for this purpose.

SAC Grid and Reference Points

The SAC provides two types of reference points: Correct Zero Position (CZP) and Personal Zero Position (PZP). Understanding these reference points is important to understanding what the SAC is and how it differs from boresights.

In the Training/ Basic Rifle Marksmanship (BRM) environment, the small arms collimator can be used to reduce ammunition costs and range time associated with initial zeroing. It has also been shown to improve marksmanship scores. Additionally, frequent use of the SAC emphasizes the importance of maintaining a good zero on weapons at all times and develops the knowledge and mindset needed to use the SAC in operational units.
