even palmer will have a different opinion on their own barrels, depending on who you talk to.

one of the onwers won't play without a vented barrel, the other goes non vented...who know?

The difference is not much in accuracy, your eye will never be able to tell the difference. the main difference will be noise. you are already used to a louder barrel with the flatline. plus, who cares if they hear it shoot, they will probably already be dead
