| I have been looking at a lot of he pictures on the site, and have fell in love with dimpled barrels. Who does them? Or are the manufactured that way? |
| You can have ADCO dimple the barrel for you. KAC came up with the idea when the utilized it on their PDW. The dimpling, while it looks cool, doesn't do any better than fluting which comes out costing less. Dimpeling will increase the surface area of the barrel, so it should cool faster. It also lightens the barrel somewhat. Fluting does the same thing.....but better. More metal is removed when fluting so the barrel comes out lighter, surface area is increased so cools faster and costs a group less. I'll admit, I originally wanted the dimples, but after researching it for a bit, the fluting made much more sense. Good luck either way. They look cool, but that's about the only thing it has going for it. |
There is a barrel brand out of AZ that sells them pre-dimpled.... the job does does not look too hot and the dimplies look shallow and far apart. ADCO does it. Marvin (SR47) here does them in the KAC pattern. He did mine. You can get the fluting and dimples done different, in depth and pattern. I doubt the above is true in most cases (although it may be adco, b/c have dimples in line, and their fluting pictures are much deaper than what you get with other shops or on most factory fluted barrels), I think with the KAC style it is probably lighter and more rigid and fluting, but not by a huge margin. You could certainly make the arguement that standard fluting is a better value, same could made with profiling vs any type of fluting. My 16" midlength weighs the same as a 11.5" HBAR or standard (.750) SS barrel would weigh, about the same as a m4 profiled 14.5".

You can...and ADCO has some great barrels....but they will pretty much work on any barrel you send them.... Ask them in their forum ADCO Industry Forum |

| If the depth of the flutes and dimples are the same, the fluted barrel will weigh less as the metal that rides between the dimples is removed. With that metal removed, the surface area is increased. As far as rigidity is concerned, there are enough threads on that issue already without starting a new one. As far as if it needs to be a Adco barrel for them to work on it....no. Mine is a Bushmaster and came out great. The time span from shipping to return was under a week. Extremely quick! Good luck either way. |
