Magpul MIAD/MOE Battery Storage Grip Core, Holds 2 CR123A Batteries

who you can see eight ar-15 I've been building up I've added quite a bit of hardware to it I hadn't flip up sights optics I've added a front hand grip I had a flashlight with remote switch a me AG grip and also a CTR stock from Magpul one of the things I am going to change out here is I'm going to change out this oil bottle this is a storage area that fits into the bead grip this is the bottle that comes with that grip I'm changing it out for the grip storage core that holds batteries when you get this this is designed to hold two double-a batteries or to triple-a batteries and there's this little spacer in here that you can push down into the top and hold the smaller batteries if you push this down in there to store the batteries to put the lid on it's going to be pretty tight and tough to get out I'm not even going to use that I'm going to only use enough space to storing these batter
