I've owned my Madbull v.2 for a while now and I would just like to hear from other ppl how reliable this is. I play at an indoor field that have an Xcortech chrono, and I usually fail with my gun (said gun also have an inconsistent fps issue). When I chrono it @ home it's hitting the right fps limit for the indoor field. When I use the field's chrono, my gun fails. Also, is there a way to calibrate the v.2 Madbull chrono?
