Internal porting?

[confedman75]

would a barrel that is internally ported be more accurate than a barrel that is normally ported? by internally ported i mean pretend putting a hallow block around the ports so the air still goes foreword but not behind the ball, rather than going 90 degrees out of the barrel, like normal porting. The air(with internal porting)would exit in the same direction as the ball.

I was thinking it would be more accurate because the air would be still filling the vaccum behind the ball, for about a foot or two, after it leaves the barrel, the time when the ball is going its fastest.

what do you think or know?

Going to take a visual shot at what you are getting at.

==== <-- Outer barrel
---- <-- inner barrel

I'm curious as to the effects this would have as well, since the air is not just immediatly lost into the open air.

hmmm

I can envision the machinery
needed to do this job, but I
am not sure of the benefits
of this design.

I think there would be turbulence generated behind the
ball. This could help lower the pressure behind the ball, what I
don't relly see, is how this would be better in any way than
standard venting?

Are you trying to slow down the air behind the ball instead of
lowering the pressure? That sounds like another way of
killing the same bird. But hey it may work.

That is a slinecer. It would make the gun more silent.

to topsecret yes
and to crimson turky your right but i never thought fo that

One way or another, the only thing porting does is make your marker quieter.

(and possibly make the barrel look cooler. )

Porting does have a huge effect on the way the ball flys. Get a stock barrel and add some porting to it. You will see the difference.

I have, and I did not notice any difference.

Doubt it. The difference will be the paint to bore match and surface finish of the barrel.

Take a ported barrel and tape up the holes. It might make it louder, but that's all. It may increase the muzzle velocity depending on the amount of porting.

wel if it's a silencer ur screwed i wouldn't make it unless u market it as a normal barrel don't talk alot about how quite it is

generally the silencer is an atatchment but i dun know sketchy idea cool

btw ud make it by haveing it in 2 piece have a normall barel porting then have threads so u can screw on the 2nd layer

THat is not how a silencer works. A silencer takes the air out the ports and filters it through carbon discs or stell wool. What you are proposing however I do not know hte side effects. I can say that it will cause some turbulence.

[Crimson_Turkey]

Some silencers (cheap ones) have no filling. They are only covered ports.

[poopthatkilledelvis]

Thats not how a silencer works. It works by allowing expanding gas to to exit the barrel slowly thru the porting into the outer casing (which will have a volume equal or greater than the insde barrel volume), and at the same time extinguishes the flame which also causes a cracking noise from super-heating the air around the exit of the barrel. And the gun must be shooting sub-sonic ammo, super-sonic ammo can't be silenced easily.

and IMHO porting in paintball dosen't affect accuracy, only sound signature. Palmer's Pursuit has been making unported brass barrels for years and they're considered some of the best. I swear by mine, loud as hell, but accurate.

I have a silenced A-5 barrel. I put a piece of pvc over the barrel and closed up both ends of the pipe. The porting on the barrel is all inside the silencer and im nice and quiet. Well not quiet, it's a a tippy.

I am dont see why you would do this, but it could be cool...
