This barrel is really good - especially for the price. The machining, fit and finish are all great and the barrel was accurate in my limited testing at 50 yards with a cheap red dot. Having said that, I have 2 suggestions. First, cut the threads in the AR10 pattern of 5/8x24 instead of the AK47 pattern of 14x1LH. This will make for a better selection of muzzle devices to the end user. Second and less important, re-title the description to remove NATO because 7.62x51 is the NATO round, not 7.62x39.
