My Barrage full size would not stay closed without engaging the backup lock in the top of the knife. So i took it apart and couldent find the problem, so i untightend the pivot screw and turned the axis assist into an axis auto, but it has a little side to side play. If anyone knows how to fix the problem and turn my knife into a regular functioning one i would be glad, and i dont mean send it into BM ither cuz i voided the warrenty like an idiot.
