Thanks for the help guys! With all the data and aftermarket stuff out there for the disco, I think that's what I'm leaning towards. I guess the biggest, most crucial thing for me is the quietness of the gun. Should I go with the 6.5 tko brake or the gaska extension? anyone have experience with the gaska? I'll order from mac1. All I've heard is good things and this will guarantee I don't get a lemon.
