One of those small parts that solves a real problem. Magpul's MIAD and MOE pistol grips accept interchangeable core inserts, and this one turns the hollow interior of the grip into a sealed storage compartment sized for AA or AAA batteries. Since nearly every modern rifle carries a light, a red dot, or a laser that runs on one of those two cells, keeping spares inside the grip means the backup is always where the gun is.

It installs in seconds, weighs almost nothing, and takes up space you were not using anyway. Black polymer to match standard Magpul furniture.
