J&J Ceramic, they both have basically the same performance
Tippmann 98 Custom, 16" Armson Stealth barrel, response trigger, double trigger, Halo B hopper, and 68/4500 Pure Energy Compressed air tank
Draxxus Blaze, Diablo Scorched, Diablo Formula 13
It is very accurate.
This barrel is awesome. I would suggest spending $10 less on the J&J Ceramic barrel though. I find this barrel to work very good with Diablo Scorched, Diablo Formula 13, and Draxxus Blaze paintball. I have the 16 inch one, but I would suggest getting the 13 inch one instead. It is hard to move your gun around when you play woodsball with the 16 inch one.
