A properly designed tool that is worth trying
This is a tool made to fit and remove the bullet button nut. You place the tool inside the bullet button body and into the nut cutouts, and then the nut should unscrew. However, some bullet buttons are assembled with thread locker that can make removal difficult or even impossible. Some people have successfully used heat to defeat the thread locker and then removal is straight forward. Unfortunately, I believe mine was assembled with red thread locker which makes unscrewing the nut impossible even with the proper tool; mine was not meant to be removed. A different technique was required to remove mine. This tool is very well made and is fairly inexpensive, so it is definitely worth a try.
