Ammo box cabinet
I put my junk in ammo boxes and then put them in a filing cabinet. four 50cal boxes fit perfect in a filing cabinet drawer. Cleaning box, gun parts box, ammo boxes, choke box, knives box, etc.. Then I lock the cabinet and lable each drawer with lables such as "tax reciepts", "work files", "family pics"....etc. that way, it becomes a diversion safe as well.
