The internal core unit from Magpul is made explicitly for the MIAD®, MOE®, MOE+®, MOE-K2®, and MOE® AK Grips. It is designed to securely hold two (2) AA-type batteries in a self-contained, water-resistant unit.
The included internal spacer also allows for rattle-free storage of either (2) AAA or (2) N-size batteries, commonly used for EOTech sights. The rubber cap features markings on both sides to identify "spent" batteries and can be easily opened with a simple thumb push.
