Totaly true, but bore sizes are an up.
And a common misconception about one piece barrels being easier to self clean is bs. No difference: http://www.pbnation.com/showthread.php?t=2218018
"Is a one piece barrel more accurate than a multiple piece barrel?
No. Many 2 piece barrels use a front that has a larger diameter than the back or insert. This means that when the ball transfers from the back/insert to the front there is no external forces that are being placed on the ball, and the front will not cause the ball to change from its original flight path.
Does a one piece barrel "self clean" better than a multiple piece barrel?
No. We tested many one and two piece barrels with a break test. During this test the one piece barrels did not preform as well as some of the two piece barrels. We believe that there are many other factors that are more important in "self cleaning barrels" than how many pieces they have.
What allows a barrel to self clean?
We believe that the attribute that contributes most to a barrel being able to “self clean” is the smoothness of the bore. This along with matching paintballs to the correct size bore will allow paintballs after a break to basicly squegee out the broken paint, and return the barrel back to somewhat of a clean state. I will go into more detail in a later post where we post data from the break test. "
