Primary Arms AutoLive Battery Cap Features The Primary Arms AutoLive Battery Cap integrates motion-sensing illumination technology into a low profile cap that swaps directly onto compatible optics bringing a meaningful upgrade without replacing the entire sight. Designed to fit many different brands and models across the industry including popular lines like Strike Eagle and Tango 6 the cap lets shooters retrofit older or lower-cost optics with smarter power management. For anyone running an optic with disappointing battery life this cap addresses the issue directly by powering down automatically during inactivity and waking instantly the moment the rifle moves. Finished in Black to blend seamlessly with most optic housings the AutoLive cap is built as a simple drop-in replacement rather than a bulky add-on module. Home defense shooters benefit from always-on style readiness without worrying about battery drain sitting idle in a safe for months at a time. Competitive and duty shooters get the responsiveness of instant illumination the moment the optic senses motion avoiding the lag of manually powering on a sight. For shooters who already own a quality optic but want smarter battery management this AutoLive cap is a cost-effective way to extend its usefulness.
