This thing is great! This thing keeps up with my gun perfectly. I only experienced one chop on full auto in testing and that was because I forgot to turn on the hopper. I had no problem with the feed neck on my gun. Great for auto guns. I had no chops the whole day and it was a perfect fit.
Get this if you experience frequent chopped paintballs or just want a kewl looking hopper.
There is a way but you have to alter the hopper with a staple. It sounds crazy but it works. When you do this though it loads way to fast like 30 bps so unless you have an angel or high-end it will over load.
