GET A GRIP, FOLKS! (One that can store batteries is best) – Here is the YHM-9540 KeyMod Vertical Grip with Storage. It works great AND can save you tons of trouble in the field.

This ambidextrous Vertical Grip is a simple, lightweight, and cost-effective device which secures tightly to any KeyMod mounting system. The low profile design provides a positive hand-hold in a small package. Sizing allows your hand to take control of the rifle, but it’s not large enough to get in the way.

And the trouble-saving part? The compartment will fit two CR123 batteries. If you’ve ever had an optic go dead after dusk, you know how helpful this feature is!
