The easy way is to just install a Response Trigger kit from Tippmann. Technically, the RT kit is just a more efficient semi-auto trigger, but they have a "sweet spot" that'll fire full-auto as fast as the marker can cycle. I own one, and I have played with several other RT-equipped field markers, and they all work this way, so mine's not a fluke. The sweet spot is large and easy to find, too. Be sure to get a good power loader if you go this route, 'cause you'll need it. An added benefit is that some fields disallow full-auto, but still allow the RT because it's technically only semi-auto. Woot!
