Thanks for the correction. I'm not that into the mech side of things but I've had the same problems with other V2, the stutter (bad choice of words perhaps) when it stops working on single fire and you have to switch to full auto to get things working again. I was once informed that was a common V2 problem. I guess it could be any version problem.
