i was shooting crappy paint from a weekend before that was kak, and the WPD paint.until i cleaned it and used decent paint
that wasnt the stock barrel, it was some crappy Carbon fibre barrel i got with it, and its not 1/2 an inch, its about 2 1/2 inch.... but it still shoots dead straightslight thread jack but james is this another marker or is it the same one with the barrel that you sawed down to about 1/2 an inch!
