Review: I would rate this bbl as excellent for being under $40 because I don't think there are better ones out there for this price. The quality is not bad and it does have a nice looking finish. But what I don't understand is all the hype about it.

First of all, the bore is not that smooth inside. Its not rough of course, but no where near mirror like smooth. The transition step, (the part inside under the threading where the actual bore begins) can be a bit smoother.
The bore measured out to be .693 at the back, and .895 at the muzzle. I used a tool I have a work to mearsure bore sizes for shotgun bbls, chokes, casings etc. So its pretty accurate.
Accuracy is ok and will probrably out shoot most bbls in its price range. But ANY Lapco or CP bbl will out shoot it for only $10 to $20 more.
It is not made of ceramic, only a ceramic coating so it is not as fragile as people say it is. It feels fragile because the walls are a bit thinner than most bbls. It is made of T6 aluminum, same materials used on frames of firearms (Berettas, Sigs, AR-15) so its strong and rigid. Don't worry about it bending or breaking but don't run over it with a car to test it.
Its true that ceramic coatings can make a surface more slick but it has to be polished up a lot more to see real differences. This bbl has the coating but lacks the polishing neccessary enough to make it slick. But if you polish too much, the coating is gone.
Ceramic coatings can not penetrate that deep.
It does shoot chopped balls "clean" but many bbls out there without the ceramic coating can do the same.
I give it a 6.5 on the accuracy scale. I do not consider them very accurate by any means.
They are mediocre on the noise level but seriousely, does noise really matter that much in paintball? Maybe if you play 5 on 5 woods ball?
The finish is nice but it does chip easily. It is typical because of the coating.
Conclusion: If $40 is all you have, get it but don't expect it to be one of the best bbl out there. Get it because you want a bbl that is priced right, decent accuracy, and a good step up from your stock bbl.
But you are willing to spend a little more, get a Lapcot "any"Shot, or CP. They are a lot more accurate. Look through a Lapco, and compare it with a JJ. You'll see the difference in smoothness.
