Ok I have been Tired of all the posts lately about the Flatline and Apex barrels , so I'm gonna explain the principals behind both along with comparing them to normal barrels.
Basic Principal:
Backspin is generated on the ball causing a zone of low pressure above the ball causing the ball to experience a force upward against gravity, caused the Magnus effect and Bernoulli's principals, thus extending the straight flight path of an overall parabolic trajectory. Simply put it makes the ball fly in a straight path for a longer time than a normal barrel.
Flatline:
The barrel is curved so that when the ball is traveling down the barrel its top surface has to travel a longer distance than the bottom surface thus making the bottom have a higher linear velocity than the top, making the ball spin backwards. It requires a tight paint to barrel match, a long enough barrel and large enough curve to put a large enough spin on the ball. The inside of the top surface is actually sandblasted by Tippmann achieve higher friction.
Apex:
The barrel tip puts friction on the top of the ball and otherwise slows down the top of the ball, thus making the top move slower than the bottom and creates backspin. It is adjustable in the force put on the ball in the tip allowing for a change in the amount of backspin.
Rifled Barrel:
The rifling of the barrel imparts a left handed or right handed spin on the shell of the ball, however it does not cause the fill to spin. As soon as the rifling stops the fill starts to slow the spin on the ball and makes any rifling completely useless. This effect is present on the two previous barrels however to get the rifling effect the ball needs to be spinning at a much higher speed.
Normal Barrel:
The paint should leave the barrel with minimal spin. To achieve the same "range" as the Apex or Flatline you must angle you gun up, using some of the force of firing to fight gravity. By Newtons laws we can conclude that the velocity spent sending the ball up is almost all recovered as the ball reaches the same height when it hits the target, thus hitting the target with a higher velocity than a Flatline or Apex barrel. That mean that your paint is more likely to break on your target at extreme range than with an Apex or Flatline because with a higher velocity it has more kinetic energy.
Moral of the story is, buy a normal barrel and a geometry book over a flatline or an apex. While firing to the same distance an arced shot is more likely to break than a straight shot from a flatline or an apex. This is because the velocity of the ball is a vector, it has an x and y component. With a backspin barrel you only really have an x component. With an arced shot you have almost the same x component as a backspin shot except that you have a y component almost equal to the upward velocity you imparted on the ball to make it go up in the arc. Therefore an arced shot will have a greater velocity at the same range as a shot from a backspin barrel.
