The MOD2 Stock Storage Bar is designed specifically to fit on to the Strike Industries Strike MOD2 Stock, offering space for accommodate for CR123A, 18650, 18350, AA, and AAA batteries.
It’s aluminum so it can conduct electricity so you’ll want to use the included rubber pad dividers. While the bar’s main compartment is watertight, there’s also a compartment at the bottom which isn’t, giving you two sections for storage.

How many crayons does it hold? asking for a friend. 🙂
Spare 18650s for a thermal optic is pretty nice.
