The Freak offers a comprehensive selection of bores, each honed to a incredibly smooth finish. By bore-matching your paintballs have a more linear path down your barrel which leads to more accuracy and less ball breakage.
When a barrel is over-bored the ball moves around as it travels down the barrel. As the ball collides with the sides of the barrel, unneeded spin and unnecessary friction impacts the ball reducing accuracy and weakening or even breaking the shell.
When a barrel is properly bored, the ball fits snugly fits inside the bore. Since the paintball fits the bore of the barrel, the ball is propelled straight out of the barrel with maximum accuracy and minimal friction.
Accuracy is the most important feature of a paintball barrel, and the bore matching of The Freak System is the most accurate barrel available.
