Primary Arms Optics AutoLive Battery Cap—Auto-On Your Scope

According to Primary Arms Optics, one of the most popular features of its scopes is its AutoLive technology, and it’s now available in a battery cap. Designed to fit many of the company’s best-selling scopes, the cap also fits other scope brands as well. Installation of this simple device instantly adds motion-sensing features to your optics.

Featuring a slim form factor and simple design, the AutoLive Battery Cap works to extend your scope’s battery life. Not to mention, the cap adds an auto-illumination feature to scopes that do not have it built in. As a result, you can be sure that your scope is ready to go when you are, whether on the hunt or for home defense.

AutoLive is a patented technology from Primary Arms Optics and utilizes an advanced motion sensor. This sensor automatically reduces power flow after 3 minutes of inactivity, helping to reduce battery usage while dormant. Then, when it senses the slightest movement, it resumes output to full power. This allows for an “always on” option for scopes that do not have that feature built-in.

The AutoLive Battery Cap is compatible with many of Primary Arms Optics’ best-selling scopes as well as other scope brands. These include:

  • Primary Arms SLx:
    • 1-6×24 SFP Gen III and IV
  • Sig Optics Tango6® MSR 1-6x24mm
  • Vortex Strike Eagle®

Primary Arms Optics states that this list will continue to be updated. So, make sure to check often for compatibility with your scope if it isn’t currently on this list.

“One of the most popular features on our optics is our AutoLive technology,” says Stephen Morgan, Director of Product Marketing at Primary Arms Optics. “Now you can add AutoLive to some of the most popular scopes on the market, giving you the ability to leave your scope in an ‘always on’ condition, making sure you are always ready to go.”


The Primary Arms Optics AutoLive Battery Cap is available now with an MSRP of $49.99. For more info, please visit PrimaryArms.com.
