I've never mag dumped, but I've done several two round bursts and a six round burst from a loose shoulder mount with an AK. What a rush!
I also found something for the AK that might work similar to the rubber band trick with the AR. I found a way to work a pony-tail holder through the mag release to the trigger, keeping reverse tension on it. Never tried it , as bumping is not on my agenda anymore, but I found a way that probably would not interfere with the mag release lever. I've also pondered that perhaps a spring-loaded stock could aid in bump firing.
These days I shoot for accuracy and usually have no more than 10 rounds in my 30rd mag (because I like to rack the action a lot).
