Screws can loosen and even fall out of guns due to extreme changes in temperature and humidity and general use. If the bracket screw on your TX200 has come loose and fallen out, get this replacement.
Many gun owners periodically check and retighten all the screws on their gun stocks and scope mounts. The minute vibrations, both felt and unfelt, can work against the screws and cause them to loosen a little bit each time you shoot.
