Or get some of the newer Madbull versions instead of the MM not as many little bearings to loose.

Although you can typically buy them at Princess Auto if you need them.



And yea you do need to reseat it after every use, when I had mine I did not keep gas in them but just lubed the orings after each game day. There is also a loading tool you can buy for the MM versions made by KA I believe, helps quite a bit and holds the bearings in place. It is also used to push the bb's in once your gassed up and to push and reset it after discharge.
