This and the Bigshot are the best barrels ever made. They are totally efficient and consistant. Most accurate barrel ever made. This is because of the precision in which they were made and the lack of porting. They clean themselves after one or two shots. They shoot smaller paint. Smaller paint is usually tournament paint. I can get Direct Hit (best paint ever made) from Paintball Geeks for $40 shipped/case and works perfect with this barrel.
It's loud. If I wanted to be quite playing paintball, I'd throw paint, not shoot it. Sound isn't a factor at all.
Better than any $100 barrel. Barrels like that are very unefficient (overported and overrifled) and aren't made with the precision of this barrel. Buy it $30 used for $50. Best barrel ever.
