What is a bt apex barrel what does it for paintballing?

Answer 1

The Apex barrel is BT's upgrade to the Tippman Flatline barrel. It allows the shooter to "curve" the ball around or "dive bomb" over the top of bunkers by putting a spin on the ball. It also will allow the shooter to get extra distance out of a shot by putting a back spin on the ball.

How the it works is the tip of the barrel has a ridge that gives the ball a spin like a curve ball or a spin on a ping pong ball. You can get the same effect by turning a Flatline on the side.
