text: Here is another tip when sticking up of supplies. We may really have to depend on our firearms at some point. With that being said it is a good idea to stock up on parts to repair your weapon if it goes down. Most of these parts are fairly cheap. For AR uppers keep an extra bolt, extractors and springs plus a spare gas tube. These are the main parts that go wear out in the upper. For the AR lower keep a complete build set springs and pins do fail along with trigger assemblies. For your hand gun keep about the same things stocked for them also. I had one group leader tell his people to all get the same rifles and pistols in case a weapon went down. The flaw in that thinking is if your weapon goes down do you really think I will strip the parts out of mine to repair yours? This is just another thing to add to your list of prep supplies.
