I just got a nice tracker and have been thinking it would be a great brush gun. The only thing is that it is kind of long. It has a 24 barrel with rifle sights. Is there any reason that it is so long? Would I be loosing anything in the way of balistics to cut it down to say 19 inches? Cost is not a big thing I have access to the right tools and a good friend has done this stuff before so it should be free. Is there any reason not to cut it?
