You have to hold it back. Also I forgot to mention that with the bolt the fake bolt moves back and forth with the recoil but it bends itself out of shape with normal use and gets stuck. Note this is just the visual effect of blowback and not the effect you feel. The buffer is what you feel and works fine. I just disabled the fake bolt, it's pretty easy.
Edit: I spoke with 007 a few months ago when I first noticed this issue, and they had already been in contact with Bolt trying to come up with a solution. Perhaps the new gen ones will be fine.
