Any premium quality paint will do. Honestly, any paint can be used, however. I've dried it with some cheap paint, and broke 1 balls in a case of 2000. That is a 99.9995% chance of functioning flawlessly with cheap paint, not too shabby.
Moderate Sound Suppression
Comes in a nice case.
Well, I've had the pleasure of owning two of these barrels, a 14" and a 12". There really is no noticeable difference between the two, preformance-wise, except that the 14" uses a bit more gas per shot. Both of these barrels are extraordinarily accurate, and the most reliable barrels I have ever had. With premium paint, I have had NO ball breakages (although I've only had around 5 balls break in my barrels in my entire paintball experience), and only 1 with cheap paint. Hammerhead advertises that the barrel "cleans it self" after a breakage. This is not be entirely true. If you want the barrel clean, you're going to have to squeegee it. What is nice, is that you can keep shooting after a ball breakage, the first round expels most of the broken balls paint and shell, and after that the barrel retains most of its accuracy (if not all). Try doing that with a smooth-bore barrel.
Weaknesses: I don't want to say there are none, but I've tested this barrel quite thoroughly and there really are no major weaknesses that I have found in it. I ended up accidentally scratching the inside of the 14" barrel with a pair of pliers (idiot operator error) and the barrel STILL functions flawlessly. Other than the constant "What the hell is that?" from other players, the only weakness I can see is the price. It's is a bit on the expensive side. It's between $80 for just the barrel, and $200 for the barrel and full 5-fin set. You need at least one fin to attach the barrel to the marker.
The barrel does what it is meant to do, increase accuracy. It does dampen noise, and it is very reliable from my experience.
