SteveM, I thought in an earlier post you had said you don't care for the Wilson barrels. Wilson is what you get if you order a DPMS AR with a bull barrel. I have used a dozen or so of the Wilson barrels and some have been real good barrels, others have been just so-so.
Olympic also produces a 1:8 twist barrel and they are available fluted as well.
I have used almost 800 barrels on ARs over the last 12 years, about 750 of them being Olympic Arms broach-cut barrels. What I have found is that many barrel makers can make a barrel that shoots good, if you want to make SURE you will get a barrel that shoots good, get an Oly broach-cut, stainless ultra match (SUM) barrel.
When I am building a custom AR the barrel blank is not a huge part of the investment. By the time I flute the barrel, thread it, install an integral compensator, bed it into a receiver and drill a hand guard for it, I have a huge investment of time in it. That's why I use the Oly SUM barrel. It's as close as you are going to get to a guarantee that you will have a "tack driver" and that I have not wasted my time on the barrel blank.
Okoyote, If you want to compare prices, give me a call. If you want references, just ask on this or any of the other boards.
