I don't know why you people are trashing the flatlines. They are awesome. I'm pretty damn technically inclined to find out how this works, and to me it was a brilliant idea. The range IS unbelievable. It may not be 200 feet or whatever they say it is, but it's better than any other barrel I've seen before. The accuracy is good. All of you people who say the accuracy is bad, you probably just don't know how to use it. It takes some getting used to. Great barrel.
Expensive, and hard to install. I'm technically inclined like I said, and it was still a bit tricky. Tweaking the alignment may be time consuming, but once you get it, you dont need to do it again. I don't know about the expensive paint, I use sheridan in this thing in 60-70 degree weather and it works. No lie.
Awesome barrel. It works. Trust me. Not as accurate as some may think, not as bad as others might. The paint I dunno about. I use Sheridan, I've also shot some Hellfire, All Stars, Marbs, and even some Brass Eagle paint. Brass Eagle broke a lot, but what do you expect? I'm not sure its worth $110, I think that's just because it's a revolutionary technology. Better range than any other barrel. I'd recommend it for back players.
