I have used the smart parts proggressive and it almost matches up to this one.
Tippmann A-5, double trigger, response trigger, 14"smart parts linear barrel
Marballizers are the best. But other professional grade paint is most likely good too.
But for cheap paint, I like scorch the best.
Quiet, accurate, cheap for a good barrel, and looks really cool.
None. It isn't expensive for a barrel
I got my A-5 about a month ago and it came with this linear barrel. Well my first game with it I was noticing that compared to the other guns that I played with, my gun/barrel combo was so much quieter. I was popping people from far out too. This barrel allowed me to assist my team up front by getting far angles on guys that were in the way of my forward team. I could shoot really far and yet it was really accurate up close when I would play forward.
Buy this. It is only about $30 and it is a great barrel to upgrade your gun with.
