For starters I've read A LOT of mixed reviews about the flatline and really the best way to understand is to try one out.
The flatline is not a standard barrel, it imparts spin on the ball which can cause it to react abnormally compared to all other paintball barrels (excusing the Apex which is the same concept.) The Flatline is called that because it is the only barrel that actually flattens the trajectory of the paintball. Normally a paintball begins to drop immediately after exiting the barrel, with the Flatline the backspin creates what is called the Magnus Effect.
The Magnus Effects states "that a spinning object creates a sort of whirlpool of rotating air about itself. On the side where the motion of the whirlpool is in the same direction as that of the wind stream to which the object is exposed, the velocity will be enhanced. On the opposite side, where the motions are opposed, the velocity will be decreased. According to Bernoulli's principle, the pressure is lower on the side where the velocity is greater, and consequently there is an unbalanced force at right angles to the wind."
In case you didn't follow that it means that a ball the is spinning backwards (spinning on the axis parallel to the ground in the direction of movement) will cause a slight lift effect while it travels, thus the Flatline can fire a ball in a straight line and have it travel in a straight line with very little drop over greater distance than straight bore barrels.
With the physics out of the way now I can discuss the bad reviews we have here.
A lot of people are complaining about the poor accuracy of the flatline and it is true when compared to straight bore barrels at the end of their usable trajectory. A normal straight barrel is most effective at ~25 Metres where as the Flatline is most effective at ~40 Metres if you compare the accuracy of a barrel at ~25 Metres to any other barrel at ~40 Metres there will be HUGE discrepancies in the accuracy. Now, if we are to compare the Flatline at ~25 Metres to any other barrel at ~25 Metres you will see that there is no significant accuracy difference. At that range the Flatline is slighty more accurate than a straight barrel of it's same length.
Paintballs are inherently innaccurate, that's why real guns don't use ball ammo anymore. The ball causes turbulence around it's rear which tends to erraticise it's flight path. Real bullets are cone shaped with a flat back, this causes it to slice through the air rather than bulldoze, thus making them more accurate.
Another common complaint is ball bouncing. Yes, at extreme ranges and hitting soft targets the paintballs will tend to bounce, however, if you hit something solid such as a mask, hopper, butt pack, etc the ball is likely to break, unless it is really low grade paint. Flatlines have the advantage of being able to shoot much farther than other barrels, but accuracy and velocity WILL degrade with range, that has alot to do with the shape of the ball, the viscosity of the air and gravity. If you find a way to defeat these, please let me know.
The Flatline is truly suited to the paintball sniper. Don't let anyone tell you there's no such thing, I've been an Axxium Inc. sniper for a year and it is not only real, it's an advantage. Any team with a good sniper can be deadly.
If you play in such a manner where volume is more important than accuracy, the Flatline is not for you. If you play in such a way that demands one shot equals one kill then this is your barrel.
The only real downside to a sniper using the Flatline is that it's report is very loud and will easily give away your position, it is VERY important that you relocate after every couple shots.
Finally, the guns consistency is also a very important consideration. CO2 is, by nature, inconsistent and without an x-chamber you will not be shooting accurately for long. CO2 is my preferred propellant and I find that it works well with the Flatline and an X-chamber, although it can be difficult in some Canadian winters.
This product does do exactly what it says on the box. From my experience it will increase your range, accuracy at medium to long ranges, flatten your trajectory, and increase the volume of your guns report.

Anything that is round without dimples.
Big Balls work fine if they're not old.
Adds a crapload of range (>100 feet)
Accuracy leaves much to be desired.
The first game I played with this, I tagged most of the other team. I actually hit where I aimed (nothing like the stock barrel which is shorter than any other barrel I have ever seen). I was ecstatic. One game after that, I was shooting all over the place, not straight at all. I was angry.
How can anyone appreciate this peice of crap barrel that looks like a banana?
Well, I was wrong.
I've won at least five times more games with the Flatline than with any other barrel. I do shoot straight when the barrel is clean and on right. The only problems I can really bring forward is that when the Flatline isn't on straight, it shoots all over the place. It also shoots all over the place when you're using balls that have dimples in them (old balls).
When you take out the barrel to clean it, make sure you put it back in completely straight, or the balls will always shoot curved.
Overall, if you're thinking of this barrel, only get it if you're willing to spend at least 50% more money on quality paintballs, not the cheap old stuff that the store has on clearance.
I'm rating this a 7 because it's so temperamental. I love it, but when it's not used exactly according to what the directions say, it's a total nuisance.

I was worried about getting this barrel because I had read mixed reviews about it. (from this very site) Fortunately, my fears were founded in n00bish trash-talking. This barrel is amazing. Most rumors/myths have been debunked already, but I have something I'd like to add.
Special Ops Paintball, on their site, claims that the flatline is not a good "sniper" barrel because each paintball is slightly different and therefore, each shot will be slightly different. This is true for any barrel. They go on to claim, however, that the difference between shots is more pronounced in this barrel due to the spinning of the paintball. This is not true. With a good, consistant air source and good paintballs, this barrel is amazingly accurate. It's even OK with CO2, but you'll get bad shots due to velocity spikes.
Another myth involves installation. I had this thing installed within 5 minutes, and that's without instructions. (As guys, we aren't supposed to use them anyways. What if someone had caught me?) Anyways, there is a barrel adapter that you have to screw in. On some older guns (like mine), the threads won't go in all the way.
All you have to do is:
1) loosen the 2 screws closest to the barrel (1 in the front handle, and 1 by the front sight).
2)insert a large allen wrench into the NON-THREADED SIDE of the adapter and screw it in the rest of the way.
3)re-tighten the screws
4)put the shroud on and insert the barrel
5)put screw into the barrel adapter and test-out the gun. If it's shooting crooked, twist the barrel until it shoots straight.
6)re-tighten barrel adapter screw
SERIOUSLY, IT'S THAT EASY!!!
This barrel, when set-up right and fed Marballizers, is extremely accurate and consistant. I would recommend it to most woods-style players, although speedballers could benefit from it too. (thus the flatline autococker, which is unfortunately no longer made) However, due to the relatively slow shooting rate of the 98c (compared to electros), I would not recommend it for speedballing.
Anyways, unless you're a total n00b, you should be able to get this thing set-up right. Just make sure to hold the gun vertical and it'll shoot straight. Eventually, you can learn to shoot "around" bunkers (to a certain extent) by tilting the gun. I would recommend this barrel to almost anyone. It is the best upgrade I have ever gotten for my marker, and the only other barrels I would even remotely consider using, other than the flatline, are the stiffi and the hammerhead.
It gets a 10 because while it's a little louder than I'd like, nothing's perfect. This is as close to being the perfect barrel as I can imagine.

When i first bought the flatline i knew it would be hard to install. I took the plastic part off, it looks like crap but shoots far and accurate.Hard to but if u know how to put it on, u wont have any trouble. I would recommend it to anyone who has the money.
Overall its a good barrel. Little expensive but worth it. I give a 10-10.

8.5" tippmann 98 stock barrel
11" werks custom pro stock barrel
14" Smart Parts Linear Barrel
Tippmann 98 custom
Tapco T6 adjustable CAR stock
scorch, premiums, marbalizers
-Accuracy (not amazing though)
-better trajectory for shooting through brush
-Takes more time to remove and attach than a standard barrel
-Requires thick shelled paint
This barrel does as advertised but you sacrifice the simplicity of being able to simply screw off your barrel quickly. The accuracy isn't perfect but the range of this barrel is unmatched. As long as you are not simple, you should be able to install it relatively easily and find a velocity that will cause your balls to appear to "float" towards their target.
Many people say that the 98 flatline is inferior to the a-5 flatline, but I've found they both work similarly well. The people who say that usually were just turned off by the slightly more time consuming installation of the 98 flatline- but performance wise this flatline works as well as the A-5 flatline.
It is good but has its disadvantages.

POS up front if you ask me. If you are in back, make sure to fire in three round birsts. Windy days are not the best times to use it, and in woods ball it will not hold up to its purpose because you cant shoot around trees, and through vines. If you buy this make sure to have nitro because it eats up co2 fast.
If you buy this make sure to be in back, because if you arent, its not worth the money.
i have used a 16 inch armson stealth barrel and i have used many other barrels on other markers, such as freak, stiffi, cp, all american, A5 flatline, tippman sniper barrel, J&J, stock 98 and stock A5 and stock imagine and stock xtra and stock ion and others im not sure of
Spyder Fenix - J&J ceramic barrel 12 inch, egg2
Tippmann 98 custom - flatline, car stock, egg2 and response trigger
soon to own a promaster
i recomend non rec balls, any higher end paint.
big-hard to get around stuff
loud-not good for my sniping habits
chops-its paint picky
accuracy-shoots fairly well
distance-i could shoot straight over the whole field
intimidation-scares the hell out of my friends
i have used this barrel on my 98 for a long time, and it had served me well for the first while i had it but later on its come loose and now its chopping allot. i could lay on the top of the British tower at paintball usa and hit the guy in the other tower by aiming about an inch above his head instead of a foot or so. its not that quiet and the response trigger doesn't work so well on it, it can if you use the right paint but i don't buy that good of paint. it shoots fairly straight, it had about a 9 inch spread at about 60 ft using full auto with the response trigger, it was much better in semi, about a 1 inch spread or so. so ya
I say that you should get this if your a serious woods-ball player or a new guy that wants a long shot so he can be a good sniper. Its a good sniper barrel i recommend it as long as you have good paint.

Tippmann A-5 w/ flatline
2005 Spyder Electra
Tippmann Pro Carbine
Tippmann 98 custom
Metal shroud for flatline
Pro-team rifle stock
Allen expansion chamber
6 inch hose
Ricochet 2K hopper
Any tournament grade paintballs
Addes significantly range and accuracy.
Plastic shroud bends when put under stress.
I have been using the flatline for over a year and it is incredible. With it you are able to really reach out and touch someone. They claim it adds 100 feet guaranteed but it seems like it adds like 200 feet.
I purchased the metal shroud for the flatline. Its aluminum so its light and more durable than the plastic one. I had a problem with the plastic shroud after I put on my pro-team stock on it. It caused the shroud to bend to the right. The metal shroud prevents this and the barrel lines up making the gun more accurate.
The metal shroud is good but it does not have any sights on it but you can use the sights on the plastic shroud w/ a mask on anyways. The thing that is really weird about the metal shroud is it has no button to realse the hopper elbow. I have to use an allen wrench to press the foward sight down to release the elbow.
The metal shroud is a must buy for the flatline
Significantly adds range were other guns can reach you. The metal shroud for the flatline is a must buy.

None that compare. The new Apex is similar but havnt used it.
Tippmann 98c Response
72ci 3000psi Pure energy nitro tank
Spyder Shutter stock
72ci 3000psi Pure energy nitro tank
Zap ZXS 200/Winchester Laredo 80 Pump
PMI Stingers worked surpriseingly well. no breaks. the rec /recyeled draxxus (not sure, came in white box) broke often
I got this barrel used for $75 which was a good price. i tested it in my yard and saw major range increases. the first time i shot i noticed the "second wind" given the ball (dips then backspin carries it back up). but after that, i didnt even notice it (eyes playin tricks maybe).
I put accuracy as a pro and con because it is more accurate than my other barrel but at longer ranges it's accuracy decreases (curves to the sides sometimes but tahts far out. maybe 235 ft)
I also put the look as pro and con because i like its look. more of a rifle feel but others might not like that.
Installation requires more work and tuning than other barrels (not just screw in and shoot.) It requires the barrel adaptor-like part screwed in so the clamp screw is on the bottom. then the shroud is put on the gun, requiring the rear sight to be removed, and the shroud screwed in. then the barrel is pushed in through the shround and into the clamp. now here is the tricky part, the small porting indentation on the muzzlebreak should be lined up with the front sight (if off, the balls will curve).
Flatlines are a little picky and not for the newbie...well, maybe an experienced newbie...but all in all is an amazing barrel. With that said, i give it a 9 because it isnt perfect and not for the newbie. plus, there is another barrel out there sort of like it (BT Apex)
Marbleizer (not as good as I expected)
Gameface (draxxas) scorch really worked well, also cheap
Range and accuracy increased as promised
Flimsy plastic shroud
I bought this for $95 (US) at a local paintball shop and am glad that I did. The Range and accuracy of my marker increased just as promised. If I can see it, I can shoot it. At longer ranges it helps to aim for mor solid targets (like packs/harnesses, marker/hopper, or mask) to avoid bounces.
Still no breaks after a couple thousand balls, so I haven't had to field clean it yet (knocking on wood).
Setup was easy. (just take your time) I took the reciever body completely apart and just set the barrel adapter in position rather than trying to screw it into the reciever.
As reported, the plastic shroud is cheap plastic and thus FLIMSY. Tightening the screws that hold the two halves together helped firm it up a bit. Just be careful not to tighten them too much, the soft plastic will strip easily.
Installed correctly, this is an awesome upgrade.
shop around and find it for less then $100.
Flimsy plastic shroud is disapointing and is why it only gets a 9. Seriously, couldn't it be as strong as the cheapest hopper or tube?
