The accuracy of this review is disputed. Please see discussion below.

Paintball
Experience:
2 years
Similar
Products Used:
No other actual rifled barrel. I have a 14" Tippmann Sniper Rifle Barrel, Flatline
Marker Setup: A-5 w/ E-Grips
Straightline
68 cu. Pure Energy Tank
Remote Line
Strengths: Accuracy, Mil-sim look, 3 ball sizers.
Weaknesses: Extremely Loud (reverse porting)
Review: The barrel has a good mil-sim look to it. Flat finish will not give away your position when camping. Changeable (purchase separatly) suppressor.

*Accuracy*
- Consistant ball placement at 60-70 ft.
- Accuracy went out the window when you break a ball. Luck to hit something 20 ft. away, takes 30 -40 ball to shoot clean. Hard to clean suppressor.

*Distance*
- Increase in range vs Tippmann 14" sniper barrel (+15 to 20 usable feet)
- Does not shoot as far as flatline, but more accurate

*Noise*
-Extremely loud compared to other barrels, not to bad down field (opponent direction) but the reverse porting makes the shots very loud. In scenerio ball the barrel really draws attention when fired.

*Paint Visibility*
-Interesting comment from a teammate here: He said that because of the rotation, it was extremely hard to see the paint coming. (Ball has noticable rotation)

*Paint Breakage*
- I shot a case of paint through this barrel during a scenerio, the paint was diablo. The gun/barrel was breaking every 30th ball when ramping. Annoying to clean with the rifling. Slowed the firing down and the breakage ceased to be a problem. Note** other players had issues with the paint breaking as well, not sure if it was the crappy paint or the barrel. Some might argue that I should try other paint but most of the time you are limited to field paint at fields and scenerios
Conclusion: Good barrel. Improved Accuracy of standard/moderate upgrades. Not tested with another high end barrel. The eight rating is from the noise and paint breakage.
Rating:
8 out of 10

Dispute:
I'm disputing this due to two affirmations:

1) Distance: no matter what the ad says, if you don't give the ball a backspin, it won't fly any further than any other straight barrel. Are you sure you are chroning the gun with both barrels? Simply switching barrels won't do: each barrel needs a particular velocity adjustment. If you get more FPS in the straightline, it will definitely fly further (just because of the higher FPS, not the barrel)

3) Paint blurryness (or something) - assuming that you or your mate can actually SEE the ball rotating, makes me want to doubt the whole review. You assume that it rotates because the ad says so.

Hope you come and explain a bit more, because this review as-is is just not accurate.

Cheers!

Candymanson, are you sure about that distance thing? I know I'm ill informed about such things, but I've heard from many people that to an extent, longer barrels will carry a ball further. Maybe thats just a technicality and they mean it'll go straighter further, but I know with my experiance my stiffi 14inch seemed to have a hella lot more range than the other barrels the guys were using (and of course was more accurate) but I could sit back and long ball em and thier balls were innaccurate or falling short.

Maybe this is irrelevant, but I know for example a 10 inche of barrel has the least length for a ball to reach velocity, and after 16 inches you don't gain anything and in many cases lose. Could this have something to do with it?

Muzzle velocity is what determines the distance. No matter a 8'' barrel or a sniper 22'', 300 fps is always 300 fps. You may lose (I really believe so) velocity in a 22'' barrel, meaning that for the ball to reach a 300fps muzzle velocity, it probably reached a higher velocity inside the barrel. But as the ball comes out it doesnt accelerate any more, in neither barrel, so muzzle velocity will be the highest velocity of the ball.

And again: 300 fps means same velocity and same distance for any given ball coming out of any given barrel. Give or take some feet due to environmental conditions, of course!

(((this doesnt apply to barrels that apply a backspin on the ball - flatline, apex, etc)))

Ok I see what you're saying. One question though, and I'm sorry I'm always seeming to contradict you or whatnot, I'm just asking questions because you seem intellegent enough to answer them well.

My question is this; I have little experiance chronoing guns because I tend to just run around in the woods with my buds, but don't different barrels have different fps when you interchange them? Not always or to a lot, but sometimes. I'm not sure which way that goes, but I wonder if that combined with barrel length is what causes people to say longer barrels have more distance (to an extent)

I do understand what you're saying though, if chronoed properly the balls all exit the same fps so then it's really just the paint, barrel, and all that crap that makes the ball fly where you want it or go crazy.

Swapping barrels will most of the time cause fps variations, due to bore differences. Different barrels have different bores, and imagine what happens when you mix different paintballs in a hopper! A smaller ball (in relation to the barrel bore) needs more gas to accelerate to 300 fps, so if you swap to a smaller-bore barrel, a tighter fit, that same ball might have an important velocity increase without touching the velocity screw.

Same happens with lenghts and porting aswell. A particular case I chronoed myself with my SP1: I chronoed 300 fps with the Opsgear fluted 18'' barrel (no porting) and when I swapped to the stock SP1 barrel, it chronoed 275 fps. Meaning? Porting uses more gas, barrel might have a bigger bore, a short barrel might not be as efficient... a lot of things.

That sort of things can cause confusion in a lot of people! Opsgear markets that barrel like a "sniper barrel": you go and chrono your SP1 with the stock barrel at 300fps, and end up firing 320 fps (maybe) when swapping to that "sniper barrel" and maybe even shoot a little further. But people don't have a chrono in hand when testing and posting reviews, so that's what makes all this a continuous struggle between the forces of good and evil.
