Dude, it isn't just some videogame fantasy. The idea behind a nerf barrel is that for as long as air (compressed or plunger generated) is pushing on the dart, the dart is in the barrel. But the second the plunger stops moving or the compressed air has all been released, you want there to be no more barrel at that point. So for some guns (HAMPS, big blasts, PASes, +bows, etc.) the absurd ammount of air requires a longer barrel.
Is my explanation making sense to anyone else other than me? Or am I jsut completely off base?
I am sorry, I typed wrongly.
It should be: "Yes, I agree getting a longer barrel might not get better accuracy."
You have a point there.
I am keeping an open mind on this issue.
