[dontask]

My stock tm aug has been giving me quite a headache lately first with misfeeds and now this:

On full auto it will stop automatically after a burst of 10-20 (will give out more shots when the battery is at full charge... don't know if this is relevant or not)
and when it does this the motor makes a weird sound once or twice(kind of like a sputtering sound) and stops
but when I repull the trigger it will shoot fine again (unless I do another full auto burst in which the same problem will repeat)
On semi the gun is completely problems free but I'm just worried if this is something to be concerned about.

The mechbox has been opened once by my gun doc regarding the misfeed problem but he's too busy lately to take another look for me
I just want to see if anyone knows what the problem might be before I crack open the mechbox

Any help is appreciated thanks!
