porting?

[yeahthatsme]

whats porting for exactly?

[Mossman]

It quiets down the barrel.
It also is supposed to equalize the pressure behind and infront of the ball. While I personally have had better accuracy with ported barrels, some people rave about non-ported barrels.

It also makes the barrel less efficient. And prettier ;)

[Kevmaster]

the VERAFIABLE effects are:
1) less efficient
2) less noise

the manufacturers will claim that it makes it more accurate, i dont see how, but they claim it is

[Load SM5]

It does nothing for accuracy but does quiet the shot.

a barrel stops affecting a paintball after the first port from what i understand. so if you have a 12 inch barrel with 8 inches of porting you reall only have a 4 inch effective barrel. you can read about this in toms tech tips here on AO and in APG
