I am thinking of buying this rifle:

www.gunbroker.com/Auction/ViewItem.aspx?Item=226804822

Even if I don't buy this one, I want to settle once and for all if fluting a barrel done post-production is viable and problem free, if done "right".

This is a 16" triple lapped SS "T" model. tapered under the handguard, fluted past the block, aftermarket. This gun is very close to exactly what I want, the mid length being the crucial factor for me (I just don't want a full-on carbine, and might be getting a barrel upgrade in the future, but want a working gun until the exact barrel I want is installed). The one thing that troubles me about this gun is that it might be a flute related lemon once a few rounds heats up the barrel... and this gun is being dumped (like not a few used guns being sold anywhere)...

Flutting the barrel post production is viable if "done right" Can't really tell you if it was done corectley with out measuring it! looking at it up close, or shotting it as you mentioned. If the gun is being dumped pay the price you are comfertable with and plan on installing the barrel of your preferance! Are you going to be putting alot of heat into the barrel or what will you be using it for?
Otherwise it should be good untill you get the new barell installed. Unless its:sick:

Well as to the use of the gun when I'm done... I want an all-around, first rifle of my personal gun collection that at first will need to fill any and all roles. Hunting whitetail/other medium or large game in any typical condition/range, tactical family defense in any and all scenarios (but not peacetime home defense, that will be covered by something else), target range practice, perhaps some amateur target competition, and I chose the AR10 platform in .308 because of it's modern reliability, ammo availability, accuracy, and durability, and ability to fill all the roles of basically what the SASS system was developed to be able to do.

As far as the heat I plan the gun to be dealing with, it's not fully auto, and only rarely will I practice clip dumps on it, basically I'll baby it and not stress it much till I have to... if the SHTF... the reason I want fluting is because I want heavy profile but lighter weight, and have the benifit of better heat dissipation as well as a stiffer/per pound barrel. Ultimately I will probably go with an 18" Noveske barrel, polygonal rifled SS, full fluting, with a switchblock adjustable gas block... and get one of these silencers opsinc.us/product.php@prodId=12thpssar10sr25.html
fitted to it, and hopefully get it and a muzzle brake using the same quick connect system. Anyway, I'm going to start another thread about the build I'm thinking about... I want to talk specific barrel lengths and harmonics and velocity and rifling etc... if I'm going to have a custom barrel made by the likes of Noveske... I want to decide it's parameters for good reasons down to the millimeter... thanks for your help Akai...

ADCO is a quality shop. They sold and installed the custom 22" extended gas system barrel for my AR10. I have also bought other uppers from them for my AR15 platform rifles. They have an excellent reputation on AR15.com and they have a board on the industry forums there.

All that said about ADCO being a good shop, I agree that rifles with "problems" are much more likely to end up for sale compared to rifles that work perfectly. Same is true for used cars. Why don't you e-mail the seller and ask him two questions: 1) Do you have any accuracy data or target pictures? 2) Why are you selling the rifle?

Good Luck

I am not sure I would trust it unless it was done by a competent gunsmith/ machinist using a proper milling machine, but if you were to get it and buy another barrel later, have you looked at the spiral fluted ones? They have the same strength but are lighter than the straight flutes.
