Small but essential. Just don’t try to charge it.

CR2032 batteries are the unsung heroes of the shooting world. They’re not flashy, but they power most illuminated reticles, red dots, and other low-draw optics that make modern shooting a whole lot easier (and more fun). That means they also take a beating—left switched on, flattened in cold weather, or blamed when someone forgot to remove the protective film during installation (yes, it happens more often than you'd think).

These aren’t special batteries—but they’re absolutely necessary. So if you're picking up a red dot or illuminated scope that runs on a CR2032, grab a few of these while you're here. Trust us, future-you will thank you.
