sweDaniel Posted April 11, 2020 Share Posted April 11, 2020 Hi there! I have recently bought a tippmann M4 with some problems on it. 1. the exit speed seems a little low. I barely gets up to CQB. The bullets seems to drop very quickly. So he thinks it’s the hop-up. 2. The owner changed the pipe and hop-up rubber and for some reason it won’t work. He have changed back to original but still the same. He also thinks that he didn’t install it 100%. This is my first HPA gun. What do you guys think it’s the problem Link to comment Share on other sites More sharing options...
