you're shooting a round gell filled ball, there isn't any "magic" barrel that will make it a tack driver. stick with a J&J, bigshot or progressive they are all good barrels for the $, the flatline will buy you some added distance but accuracy past a conventional barrel is questionable.

I'm pretty sure it'd be just as accurate as any barrel if u had the right paint match to go w/ it.

 would like to add that I currently use a flatline and before purchasing I always do a lot of analyzing. I will not come out and say that the pro's and con's for the flatline are correct or incorrect because I have noticed that everyone is entitled to their own opinion. which in turn is what one reads. I will however, both agree and disagree to many comments I have read in numerous reviews.

I have had my flatine (A5 Stealth package) for a week now and have had the chance to put it to fair use for woodsball. People say that it is not accurate, remember, how the flatline works. You are going against gravity with a backspin which results in a flat line. Now for those of you who with not much experience taking it apart, there are some factors involved such as interior barrel alignment and mounting. when I received mine I had noticed that for something that should be "out of the box" the barrel was mounted incorrectly. The top screw was not aligned with the sight and when I turned the barrel completely to the right for mounting, same problem to the other side. After correcting this (centering and tightening screws) and practicing for a while I still found odd that I was having problems with accuracy.

I decided to read a little further and stumbled across FPS issues and set my marker for 280. I have been happy since. I am still messing around with paint to find the best combination available in my area (Puerto Rico) and have sort of narrowed down a comfortable setup. No marker is perfect right out of the box and like practically anything out there, fine tuning and getting used to will always have to be done.

My reply is based on the fact that everyone has their own opinion somethings work and some things don't. Now learning off of other peoples experiences makes things alot easier.

I will always recommend reading several forums and numerous reviews.

Do not always believe what the sales pitch says, that's what it is, a sales pitch.

Would it compare good w/ the interceptor??? Is the interceptor a good barrel as well?

• Cleaning the barrel after every game whether I broke paint or not.
• Readjusting the barrel and red dot sight at the beginning of every  paintball day.
• Spending extra money on top quality paint.
• Flipping any leftover paint every day between paintball days.

• They are very climate sensitive
• Breaks increase below 70 degrees.
• Hard cross/headwinds do ugly things with the backspin.
• Excess humidity also causes me problems, although I don't know if it is because of condensation swelling of the paintballs.
  
• When paint breaks in them you are totally and completely hosed for accuracy until it is thoroughly cleaned.
• You have to know how to use it.
• It's not a long range sniper barrel--at the longest range it is much more useful for suppressive fire
• The F/L has to be installed perfectly straight
• Any left/right tilt in the installation will cause "curve balls".
• This needs to be constantly checked--no matter how tightly I put mine on I always end up readjusting it before the next time I play.
• You must hold the marker perfectly level when firing or you get "curve balls" due to the spin being imparted off-center to the trajectory of the paintball  (sometimes this can be very useful though).
• It is not a speedball barrel.
