View Full Version : Question On Barrel Porting.......

04-02-2006, 04:01 PM
OK I saw this great barrel yesterday and it was a 16" with porting going half-way up the barrel...I know that with more porting, the more air you use...so would it be posible to tape some of the ports up? To make less ports? It would save me air and MAYBE shoot the ball farther. Does anyone know for sure if this will work or not?:D :confused:

hypetheticallly...yes. The less air being redirected out of the barrel ports, the more that's behind the ball. If your marker's regulated, you could feesably reduce the input pressure to compensate for the extra air behind the ball

edit......it's going to be loud as thunder though.....lol

the dif between 14-16 inch barrels is nothing its the finish on the inside if the barrel is what counts.

i hate people that go to paintball and do know anything about it.

...So ur saying that its all the finish inside the barrel, and that extra two inches has nothing to do with anything??? You dont think that extra two inches is a waste, and does more harm than good???

I see ur point about hateing those that dont know anything now......

BTW, nice job on wakeing up some very old threads!

Ok, no reason to hate on those who know nothing about the sport. It's guaranteed they'll know more AFTER YOU ANSWER THEIR QUESTIONS.

We all were there at one time...

By the way, it is NOT all about the finish in a barrel. You're right, there is no difference between 12-14 inch barrels. And sure, the finish has a little to do with it. The smoother the finish, the less friction involved. But to say it's all about the finish is incorrect and NOT helpful to anyone. A ball to barrel match is MUCH more important in efficiency than "finish." Most barrels these days are polished smooth anyways...and some are impregnated with ceramic or teflon.

It's the first 6-8 inches of the barrel that's important. Those first few inches are where the force and direction of the ball is guided. The final inches are guidance related. If you have a good ball to barrel match, air shouldn't escape around it as much and you could hypothetically use less air. If you have a long barrel with a lot of porting, you can tape them shut with electrical tape. That's what I did with my J&J...

Druid's right. It will be as loud of thunder though.

I agree with viking. The paint to barrel match is very important. Maybe consider a pipe kit or something along those lines.

just so everyone here knows or whoever doesn't know wants to know ... paint to barrel match is where you stick the ball in the barrel and you can just push it though ...

Not where it just rolls through ... or it can't even fit inside (leads to barrelbreaks)
