Its pretty accurate. Never had any problems with breaking paint. This is the base model of the Palmer barrel series. Its brass so get soem Brasso and voila the barrel looks like gold. Accepts a wide variety of paint. But once in a while I guess everyone gets a bad batch.
Weaknesses:
Again its brass so it will tarnish. and also since it is brass I would use it as a shovel.
Conclusion:
The barrel I tested was 12" in length. I used it on a Autococker/Sniper. I tried just a mix. In other words I took what was left from all my other trips.(Big Ball, Marbs, All Stars, Nelson) And then I mixed it up and put it in my hopper and the accuracy was about the same. For 50-60 bucks its a nice barrel to have but I do recommend you at least vent it but that is another 39 bucks. This is a great barrel to have. But again I do recommend venting it and maybe have them put a finish on it. Perhaps Nickel or Powder Coating.
"And also since it is brass I would use it as a shovel."
WTF are you talking about? One of the reasons why this barrel is so good is BECAUSE ITS MADE OF BRASS. Brass is THE BEST material yo use for a paintball barrel, tool.
