    The Mil-Spec AR-15 pistol grip is hollow, and open at the bottom. Back in my Army days you could get a plastic cap that fit over the bottom, thereby making the hollow space in the pistol grip suitable for storing small objects. This would be an ideal space to store a spare battery for a red dot sight, for example. Does anyone have a link for such an accessory?
