I have a couple of their light weight profile barrels that I got for around $50 or something back a while ago.

I have one of them installed on my rifles and I only have about 50 rounds through it. They are nitrided and the bores are quite dirty. I think I was getting around 2 moa with some potential for better. I just think I need to shoot more through it and break the barrel in more than an other barrel.

I read somewhere that they are capable of good accuracy, you just need to break them in real good and they'll settle down.
