Milsim meathead co-worker is convinced the 18" on his TM-15 gives him more distance than the 14" on my rail.
I disagree. If anything I think the extra 4" of traction slows him down more which=less distance
Am I wrong or is he wrong?

If the two guns are chrono'd at the same FPS, they will both have the same range.

i know the flat line barrel does give a longer range if im not mistaken.

Yes, but a flatline won't fit on a TM-15, or a Rail, so we're talking about two straight tubes.

if it is traveling at 300fps when it leaves the barrel, it will go the same distance as any other regular barrel (not apex or flatline) at the same fps.

Length of barrel is unimportant, the only thing that would cause that would be increased FPS or increased backspin.

What about a 3 inch barrel, or a 40 inch barrel?

As long as the muzzle velocity is the same, then it doesn't matter how long the barrel is. Barrel length does not determine the range, velocity does.

he does have the apex on his TM

The Apex adds a negligible amount of range, like 30-50 feet. However, paintballs are horribly inaccurate at maximum range in a tube, let alone maximum apex range, so the added distance doesn't really mean much. The point of an apex is that it provides a flatter trajectory. However, the more clicks you go on an Apex, the more the ball drops before it flattens out. So if you put enough clicks in, either you have to arc your marker back, or you're shooting paint at the ground.

So yes, his apex will have more range than your 14" barrel. However, his longer range is due to his apex, not to his extra barrel length. And his extra range doesn't really mean much, as it's horribly inaccurate and pretty much useless.

If you want a really good backspin barrel, the flatline is the way to go, as it puts a flat trajectory on the ball, which doesn't require the marker to be angled back.

No it does not it may be easier to point but it will not increase distance that relies on your FPS. The only exception to this would be an APEX or Flatline.

Flatlines are strictly for Tippmann markers.

My dye ulttralights haas soo much accuracy than ur spider that it shoots around walls and through glass to hit the guise on the other side.

Barrel length SLIGHTLY affect accuracy, but barrel quality is more important.

No, barrel length doesn't affect accuracy. The paint you use affects accuracy.

from my experience at least it has a very slight impact. barely noticeable but still there. Not sure why. But then again i have never used the same barrel at different lengths so there were obviously some other variables at work. So maybe my initial post was a little mis representative of the truth.

I suggest you look into PW's testing.

I show up at a field that I never been to before for some rec-play wearing cargo pants with a t-shirt....carrying a old mech Spyder and two pringle potato chip cans for pods shoved in the pants pockets. The stares are priceless and after the first game or so you get to see the grins from the ref and players who know....priceless.

To clarify, punkworks did not necessarily that barrel length/bore/etc has no effect on accuracy, only that it is sufficiently below the noise level of the paintballs themselves that it has no observable impact. Its entirely possible that longer barrels are more accurate (or precise, if you want to be picky), but the difference in accuracy is likely measured in fractions of an inch. Against the spreads we see at any reasonably distance (20 inches at 100 feet or something on that order), that difference is irrelevant.

Yeah.

But if you set the FPS to 300 with a 14 inch, the. Use a one inch, or something very small (1-8) inches, your gun wouldn't be shooting at 300 FPS. This has to do with acceleration with air and the length it takes for acceleration.

But we're not talking about something very small, as in 1-8" in length, we're talking specifically about a 14" barrel, and an 18" barrel.

That, and I said muzzle velocity, so if you set the muzzle velocity on a 14" barrel, and then switch to a 1" barrel, you would reset the muzzle velocity to be 300fps. You wouldn't just switch barrels without checking velocity, and you would adjust it to get to 300, if it wasn't at 300. So barrel length doesn't matter, because you'll set your velocity to 300, no matter what length your barrel is.

I know, that's why I said just changing the barrel, and yes I noticed why you said muzzle velocity.
Finally, I was just adding another point that sizing up doesn't (after a certain point) matter, but sizing down can (after a certain point).
He also mentioned a 3 inch barrel, do that's where my comment came from.

I'm agreeing with you, just adding another point.
