The newest addition to the GT 2000 series of paintball markers is the GTV1. New features on this gun include a ported barrel, milled body, and most noticibly, a polymer double trigger frame with wrap-around grips. The plastic frame is tough and durable not to mention more scratch resistant and lighter than aluminum. Expansion chambers are easily installed on this gun or if you prefer a vertical bottle. Of course it still takes spyder threaded barrels and all the goodies that you would put on a GT 2000. Doug Brown told me they should be out in mid April but they are running late as usual with most paintguns. I will have a huge message up on the home page when they come out for sale at NPS.
