Digital File - Packout Wall M12 Battery Holder Quad Mount (Large and Small Batteries)

Easy to put batteries in and out. Takes up the rail space around it

good product more compact thanthe original but it makes it too wide for the neighboring rail to be used. Also you can't use the slit below it either. It essentially ends up taking up the same ammount of space as the OEM. I do like how it is easier to put the batteries in and out.
