Boring paint = better "accuracy" and consistency of shots as well as better efficiency.
2 Piece barrels add a fractional amount of weight, but is unnoticeable.
People have their favorite kits, research one you will like.

AMEN!

2 piece barrels are also easier to manufacture, since the 2 halves are each shorter - this does prevent runout, but if a 1 piece is constructed properly it will be straighter than a 2 piece due to alignment.

If the ball doesn't touch the outer bore, then there is really no point in having the outer barrel except for maybe noise reduction.

Here's why bores are stepped: Air will take the path of least resistance.

In the case of large paint and small barrels, as soon as the ball passes the first row of ports, air vents and the ball starts to drag in the barrel. In some cases, it will stop before it even leaves the end of your gun.

I tried this myself, a 14" freak 2 piece barrel vs a deadly wind fiber 14".

The only difference I got was tighter grouping, by 2-4" at 60" for the 1 piece and 3-6" with the 2 piece.

I was able to put 2 shots within 1" using the 1 piece carbon fiber vs a 2" group using aluminum freak barrel. Both using 0.684 insert.

Thats what I think.

A deadlywind uses a freak insert. A freak barrel uses a freak insert. In what way, exactly, is a 2 piece barrel considered a straight bore? And, by the way, that scenario that you personally observed was all in your head. Because you used the same insert for both tests the accuracy will be the same unless your freak barrel front meets the back at a 15* angle.

Consistancy is ball on ball, every ball travels the same distance in the same trajectory.

If by accuracy you mean that a paintball will have a flat trajectory and travel exactly where the barrel is pointing - then yes, I noticed an improvement in consistency.

As long as I can be reasonably sure the next ball will hit the same place as the previous ball, with minimal spread, I'm a happy camper. Everything else can be compensated for.

So then you are saying that the second part of the barrel is primarily for sound dampening, correct?

What I don't get is this: It was proven that 8 inch barrels are perfect dor accuracy; Anything less, and the ball's consistency will be compromised. Any greater and the ball will be just as accurate, it'll just take more air as the resistance is greater. It would make sense if 2 piece barrels where broken up into an 8 inch back and a 6ish inch tip. This would insure accuracy. What baffles me is why are the barrel backs usually LESS then 8 inches? Less then 8 inches, and the balls will not have consistent accuracy.

So now someone tell me this: Why are barrel backs less then 8 inches if it was proven barrels less then 8 inches will not have consistent accuracy.

[YeloSno]

2 piece barrels are made for this reason:

Cheaper to buy/sell, which means they can gather more demand. Having multiple back bores is also easier and can be carried in a smaller container than having multiple full length barrels, which means that the 2+ piece kits can cater to a larger audience, which means the manufacturer can also sell more.


Yes 2 piece barrels are more likely to break paint and have worse consistency for the same finish and bore dimensions, but the difference is incredibly nominal.


ANY multi-piece barrel kit with a bore at least 6" and no longer than 8" that is of a high quality and consistent finish on the inside and is the right bore for your paint is perfect. Even if it happens to be a one piece with those characteristics.

[Xdanisx]

But what's the point of a 6" back when 8" would give better consisency?

An 8" back has NOT been proven to provide better accuracy, only more efficient use of air. It is debatable whether or not a longer back provides better consistency in velocity. 8" has been deemed the ideal length to allow a paintball to reach its maximum velocity in the barrel.

From my personal experience, consistent accuracy is only determined by the barrel to a certain extent. A consistent and well-honed internal finish plays a part (obviously any burrs or inconsistencies can cause stray balls), while the actual length of the back doesn't play much part (if any) in accuracy. The main factor when it comes to accuracy is the paint. Good paint is key.

A perfect example is a Disruptive Deathtouch barrel vs. a Furious Lotus vs. a CCM barrel. All 3 are very well-made, well-honed barrels, and the largest difference between them is the length of the back. The Disruptive is 8", the Furious is around 4-5", and the CCM is only 2". As far as accuracy and consistency goes, using good paint, all 3 are on par. The only differences between them is air usage and sound signature.

tl;dr: Accuracy is 90% paint, 10% barrel.

So then would a c m 2" barrel be arguably the beat becuase that allows a larger tip to disapate air and quite the ball? And is the ONLY reason for the tip sound dampening?

Not really. I personally use Disruptive barrels because of the longer back, and they happen to have a really quiet sound signature due to the porting. I don't know how well the tip's length dampens sound, but what I do know is that porting plays a large part.

The length of the tip makes it easier to aim the marker. A longer tip is also good for manipulating bunkers, and pushing through brush if you play woodsball.

False. For your money, they're one of the worst. Even with the double length sizers.

It's the back, not the tip that makes the biggest difference.


With a longer back of the right bore, you can also drop your operating pressure, which in turn makes the marker quieter and smoother anyways. Sometimes be an actually seriously noticeable amount.

[Heaton]

If there is porting then it will serve as a sound damper. Large straight bore, non-ported barrels with small paint through them will still accelerate the ball, just not as efficiently as a tight bore. You can have similar velocity consistency with an underbored barrel like you would an overbore. The specific combination of under/over, long/short, front/back is preference. Some people will tell you different, and I will ask them to show me a single example of scientific testing where variables are removed in a totally imperfect environment--nothing was ever 'proved', just speculated at best.

[YeloSno]

No, stuff was proved.
There are multiple postings and verified threads here about it.

Check in the barrels section and skunkworks' stuff.

Yea, that's what I'm saying. So if the ball is incredibly acurate from a 2inch barrel, then that leaves room for a longer tip. The longer tip would allow for more air ports and thus a queter sound.

Or ar you saying that with a 2 inch back, it would take a higher pressure to propell the ball resulting in more noise?

Up to a certain point there, right?

But there isn't that much porting on the CCM barrel. Plus, the 2" back is much too inefficient in comparison to a longer back, which leads to...

This. Bingo.

[Xdanisx]

Good discussion, chapps.

[YeloSno]

t0pher, you're ****ing awesome and I want you to know that.


But yeah, that's the gist of the situation.

Besides, most barrels, if the manufacturers are smart enough to give them a proper control bore, they'll be wise enough to make a proper tip to go with it.

Have you seen the disruptive barrels?

They haul *** with porting and bore.

[bigdogfurst]

you can swap the backs or fronts to your preference and adjust the backs depending on paint size
