good quality paint
Sizing your bore to your paint
16" tip
as your using an Axe I presume your wanting empire gear, I cant remember the name of the barrel but they make a barrel which is Male to male thread as its barrel back (control bore) is longer this guides the ball and gives it a more accurate shot these barrels are slightly better on accuracy over the Freak barrel versions as they are smaller (see image of barrel that I mean)
