So on Thursday, I came in from work and decided that I would do some work on the AR. I gathered up some parts, got my barrel wrench out of the box and headed out to the shop. When I came back into the house an hour or so later, I was going to put the wrench back in the box, which also had a carbine length gas tube stored in it, and I can't find the box! Now I live alone, and the dogs were outside, so they couldn't have moved it. I have turned the house upside down and looked everyplace that I might have placed the box. I'm about to lose my mind, I can't remember moving the box, and I'm at a loss. Do any of you guys have a trick for finding something you've misplaced? I hate to buy another gas tube, as I know that one will turn up just as soon as I place the order.
