I saw this video and thought it would be fun to build one of these.
For those that don’t know, Airsoft is a game/sport similar to paintball in which small plastic BB’s are fired from specially designed guns. I don’t expect the MG I built to ever be used for anything but target practice. This one is built fairly rugged (except for the trigger so it can easily be replaced if it breaks), and intentionally can’t generate the force that I’ve seen with other guns of this type. The barrel is made from an aluminum arrow shaft which is over sized for the BB’s. A lot of air escapes around the BB’s and they don’t fly extremely accurately as a result. I’m hoping that my brother’s family will be able to put it to use on their farm.
