I was out goofing around in my yard and I had a little bit of nitrogen just bearly enough to recock the mag so I started to play with the trigger a bit,and thats then it happend I made it go full auto like on blow backs, kind lik when a spyder or a tippmann run out of air. I pulled the trigger back al the way and then I just bearly let off the triger and held it about half way through the trigger pull, it sounded pretty sweet, but I didn't have any paint in it, casue it would have chopped every ball.
