Kaner System, CP Barrels, SP Barrels, Flatlines, Freak System
04 Mech Orracle with many mods.
Almost any, if you like to shoot real small stuff you may need to buy the 2 smaller adapters from Stiffi, but for 90% of the paint you shoot it's fine.
Lightweight, Pretty Quiet, Accurate, Versatile, everything you may want in a barrel kit.
$$$$$$$$$$$$$$$$ Crap, it aint cheap.
Got the kit about two months ago, I may have put 4, maybe 5 cases through, mostly Draxxus Rec balls. Flawless performance. I could tell a difference between my 16in Stiffi and my 14 inch Kaner instantly. Less weight on the end of my gun gave me better balance and a more stable shooting platform. Got excited and short stroked my Orracle a few times, had a few breaks. Shot through the breaks in 2 or 3 shots, no need to squeegie. The carbon fiber looks cool, but didn't match my chrome too well. It still looks good; and peformance beats looks anyday. Sometimes I feel I have to baby it, even though I know the carbon fiber is tough, it is expensive. Oh and don't use a battle swab or any kind of cloth squeeie. I rock.
If you got the $ it is worth it. Even if you have to sell your pets you won't be sorry...
