Serial number on a paintball gun?

Answer 1

What about it? If you mean its purpose, then that's easy. The serial number on a paintball gun is much the same on any gun, it is an easy way for the manufacturer to keep track of that particular gun, such as it's date of manufacture, age, etc. This makes it easy for the manufacturer to give out information about a particular gun, like if they had to recall a certain gorup of guns due to a defect. The manufacturer would merely have to tell us the serial numbers that are being recalled, and with a quick glance at it you could easily tell whether or not your particular gun was on the recall list.
