Reusable zipper bags hold various "kits" which sit inside various boxes stored in storage containers/shelving units. There are also various small boxes which contain parts related to specific firearms or needs. One shelf/unit contains all the things I need to beak down and clean all my firearms at home. This would be things that I need but wouldn't take to the range/plinking such as patches, a healthy supply of CLP/grease/oil, oil soaked rags, jags and rods, spare parts, and my trusty torque wrench. I have a box with bags assigned to different firearms for outings. My 10/22 and PC9 both have their own "range bags" which include everything needed to break down and clean/trouble shoot my firearms while out having fun. The "range bags" have bore snakes, smaller bottles of CLP/grease/oil, clean rags, allen wrenchs, q-tips, chamber flags, and whatnot for use at the range or otherwise. Inside of various small boxes are extra parts or stock parts which I save in case the aftermarket parts break.
