that is the project I'm working on since I change my PDW to open chamber, using PDW mag is okay but the M4 mag has the same problem like you have. If you take a look on the WE site "how to change to open bolt", you will see the guy testing fire is first single shots and then auto, seems like the same problem at the end but he didn't keep firing it. I think it is the design difference between PDW may and M4 mag(loose from back and fore when it kick back). I have some idea in my mind just I don't have enough time to try out yet.

Ie, in full auto 1st shot fine, 2nd drops, 3rd and 4th fine, 5th and 6th drops, 7th is fine 8 and 9 drop, etc. There is no pattern in the firing. I was told it could just be the VSR hop up as they tend not to like full auto anyway, but I've heard other stories of the guns working properly. Like I said.. Semi-auto is fine, even when I pull the trigger as fast as I can but it's only when its in full auto that sometimes the bb's have no velocity behind them. Any help would be appriciated
