The Small Arms Collimator (SAC) is a precision optical device that allows military or law enforcement shooters to confirm zero and/or re-zero weapons, to a high level of accuracy, without live fire.

Telluric Group is pleased to announce that SPA Defense, formerly SPA-SIMRAD, will be assisting us in introducing the small arms collimator (SAC) to military and law enforcement organizations within the United States.
SPA will be focusing their efforts on a SAC that is specifically designed for use with the SIMRAD night vision sniper system. This SAC, which utilizes a double spigot design, allows users to precisely check or adjust zero day or night- with or without the SIMRAD attached to the weapon.
SPA will also be Telluric’s exclusive GSA outlet.
Telluric Group chose SPA Defense primarily because of their extensive knowledge regarding precision weapons systems and optics, and because of their experience and success in government marketing and sales.
Information regarding SPA Defense is available at their website- www.spa-defense.com.
