has anyone out there modified the tube selector on the ksg12 so that it uses both tubes like the uts15? I like the ksg but it has the fatal flaw of having to stop after 7 rounds select the other tube then fire the other 7. the function of the uts15 is much better but it is an extremely ugly gun. and there is the fact that it looks like a prop from the movie aliens. any help would be appreciated.
