The advantages of the Flatline System for the M98 Custom will far outweigh the disadvantages for most recreational players. We already went through the things you get from a Flatline barrel in comparison to a normal barrel, but for those who haven’t read the previous review here they are again. First of you get more distance because of the back spin the Flatline is designed put on the paintball, then you get amazing accuracy partly because of the flat trajectory, but also because that’s what the barrel’s designed for. The thing is also pretty efficient. Here’s some info about it:
“The Flatline Barrel System is the first barrel to put back spin on paintballs. It not only increases accuracy and distance, but it also has a flat trajectory.”
And again the things half the people claim as downsides: you need to get used to the barrel – it’s different, it’s heavier so it will take some time to get used to that, it’s louder than most of the barrels out there. It’s hard to install on the gun and then it takes a lot of tweaking to adjust the settings. It’s kinda paint picky – it likes high quality paint and really hates the low quality one. It’s kinda of a pain to clean because of the rough inside finish – regular squeegees won’t do. On top of that it’s pricy – it costs about $120, but trust me it’s absolutely worthy. Theirs is a reason for it to be one of the highly appreciated barrels out there. If you’re scared from all the “downsides” find a way to test it first and then decide whether to get it or not.
