Barrett, I bought one of Anderson's 16" barrels for my Matrix 308 build. Fit and finish were great and so far function has been good too. I can't tell you what kind of accuracy it's delivering because the only shooting I've done is function testing and break in. I haven't had a chance to put it on paper yet, been busy with the holidays and such and now the damn wind is starting to blow here and will probably continue through spring like it usually does.
