The M4/ M16 Collimator Kit (5.56mm) is designed to work with M16, M4, and M27, and other similar weapons with standard bird cage flash hiders.  Users can select from a CZP (zero distance) of 100m (USMC version) or 300m (US Army version). These kits are standard US military variants. The Kit includes the collimator (complete with an LED illuminator for use in no light conditions), confidence gauge, operating instructions, and a padded, Berry-compliant pouch. They are generally in stock and ready to ship.

Small Arms Collimators (SAC) allow you to accurately zero or confirm zero on weapon systems in under sixty seconds after changing sights, after changing weapons, after compromising zero by bumping/ dropping weapons, during pre-combat checks, or at snipers’ final firing position (FFP).

The SAC can also be used to significantly speed up the initial zero process, which not only reduces range time and ammo requirements for zeroing but also creates more time for training and leads to overall improvement in marksmanship.

The Small Arms Collimator is the only device available that meets the accuracy standards of military and law enforcement assault and precision weapon systems. Other instruments have tried to accomplish what the SAC can but none have come close to the precise minute of angle (MOA) success. This means that it is the only such system that can be trusted to check or adjust the operator’s weapon system in the field without compromising the ability to effectively engage targets.

Collimators are repeatable (all SACs can be used on any like weapon system) to provide better than 1 MOA results.
