Ok i'm guessing your taking about the inside part,spring follower- wooden dowel so on.. To do this unscrew the magazine cap and very carefully pry out the metal retainer,the spring will fly out when you do this so keep your hand over it to catch it. then you can remove the dowel and follower.If your taking about the outside part than I don't know,my guess is you would have to have it pressed out with a press.
