Price is high but i got it with my Black Magic 2k1 Cocker so that doesn't matter.
1. Getting it off is a pain. the base isn't longer then the front block on my cocker and the barrel unscrews into 2 very easily.
2. Picky about paint. Doesn't like proballs or team colors very much. Zap Performance plus work alright but are still too big bore for this barrel.
3. barrel is heavy
4. price is high
5. porting is hard to clean, best way is to turn the gun upside down, fire 2 - 3 times, make sure the gun is empty then fire into with your palm covering the end of the barrel, will blow the air out the ports and clean them but still a paint in the butt
6. unlike the J&J Ceramic this barrel DOES NOT shoot through breaks, you need to clean it when you get a break. I'm going to try putting a teflon coating on the inside, maybe that will help....
This is a pretty good barrel. I got it stock so thats why I have it, wouln't spend 90 for it when you can spend 50 for a lapco bigshot which likes a much wider range of paint. If your playing tourney level or BYOP fields then this is good but this barrel is not going to like 32degrees comp or PMI premiums at all.
I'm giving it a 7 due to super small bore size, high price, and hard to clean porting
