The are very durable, but they can be bent. Trust me. This barrel is the best I have ever used. I have not tried any of the other good kits to compare. It's hard to believe they could be better. Its has alot of different boere sizes. Alot of different tips, lengths, colors and styles. I've seen just about every color and lengths from 6" to 18". Change the back and you can use it on another gun. Hard to get off a cocker, until you learn how. I've shot alot of different paint, from $40 to $80 a case. If the paint is round it shoots good. I shot some $40 paint that shot great, broke good, just could'nt see the fill.
Price 7. Accuracy 10. Looks 10. Bore sizes 10. Different tips for style of play 10.
I would recommend this to anyone who is willing to spend the money.
If you're considering buying an entire barrel kit, you are either serious about paintball or you have some extra money to spend. Either way, you have/can get the money, so everyone needs to stop with the whining. $200 isn't that much in paintball nowadays, and any gun good enough to need this barrel costs way more than that anyway. I have $1000+ in my Cocker Outkast, and I'm just getting started. Moral of the story is: Suck it up, buy the barrel, be happy, dammit.
