Hey everybody, I'm pretty angry, so I'm going to write about it. This is more or less about the constant pursuit of something better, than it is about the madbull hop-up (although I am pretty upset with it). I am always looking for ways to make my guns shoot better/farther/more consistent. I have used G&P, Systema, and Prometheus m4/m16 style hop-ups, with increasing success (in that order). The madbull hop-up seemed like a very rational, sensible design. Never worry about those pesky, cheap...
