Primary Arms AutoLive Battery Cap

It replaces the standard battery cap on your scope and uses integrated AutoLive motion‑sensing technology to automatically shut off the illuminated reticle after a few minutes of inactivity to conserve battery power, then instantly reactivates illumination the moment the optic experiences movement, allowing the reticle to be ready without manual switching. This feature is especially useful for shooters who often forget to turn their scopes off or want an “always‑on” capability for defensive or field use while significantly extending battery life.

The cap is designed with a low‑profile, compact form and durable aluminum construction that resists wear and corrosion without adding noticeable bulk to the optic. It is compatible with a range of Primary Arms SLx series scopes as well as select third‑party optics like Sig Optics Tango6 and Vortex Strike Eagle models, though compatibility varies by thread pattern and scope model. Backed by Primary Arms’ lifetime warranty, the AutoLive Battery Cap offers an easy, tool‑free upgrade to make your illuminated scope more efficient and reliable in everyday carry, hunting, or tactical applications.
