i purchased two GI mags about a month ago and finally got around to using them. ove noticed that the follower is anything but smooth while loading and will get stuck if they are put in any type of position. then while firring, the mag will catch the bolt back but then ill have the last round just chillin ontop of the mag. sometimes when the last round does chamber, the mag wont catch the bolt when empty. any ideas on how to fix em or should i get new followers?
