Okay, someone help me out here. What is the supposed advantage to a "hold open" follower? As soon as you pull the magazine, the bolt closes, right? So what is the magic with the whole "hold open" mag issue? Am I missing something here? Since you have to cycle the bolt to fire the next round from either type of mag follower, I don't see an advantage to the "hold open" type.
Maybe I'm just ignorant...
