These are a couple of threads I started but both talk about barrels and what they add to accuracy and precision.
Some questions to help decide on a barrel.
Are you shooting First Strike Rounds (FSR)? If you are, and only shooting FSRs, the Lapco FSR .683 Rifled barrel is fantastic. If you want to shoot both FSR and regular paint, the Hammerhead rifled barrels with different sized fins is a better choice. If you're running just regular paint, the Dye Ultralite barrel is a great choice but any quality barrel will provide the same level of accuracy/precision regular paint. The rifled barrels mentioned will improve long range precision of the FSR rounds. Rifled barrels do NOTHING for regular paint accuracy.
A quality barrel from a reputable manufacturer (Dye, Lapco, Hammerhead, etc) will provide the same benefit to accuracy/precision one to another. So the real choice becomes which barrel do you like best? Do you like the looks of one over another? A threaded end to add whatever tip you want? Is weight an issue for you? Sound profile of the barrel? A one piece or two piece? A barrel where you can change it's bore size for different sized paint? These are the things that will help you choose one of these quality barrels over the other.
You'll note that I have not mentioned a thing about range. Your paint should be leaving the barrel at whatever your field velocity limit is. If the limit is 285, then the ball should be leaving your barrel at that velocity. Unless your barrel is putting a backspin on the ball like a Tippmann Flatline (which I don't think they make for the TipX) or an Apex equipped barrel (many options here) then the barrel will do nothing to change how far that ball leaving at 285 fps will travel. A FSR will fly further than a regular paintball because of the shape of the round, not the barrel it is fired from. Barrels have an affect on accuracy/precision but not on range except for the two mentioned above.
