Probably the best all around barrel on the market for the price - Noveske Lo-Pro Gas Block 5.56 Barrel

It's a Noveske Barrel. That sentence alone should impart a feeling of reverence in the presence of greatness. Is that hyperbole? No. They punch above their weight, and always deliver consistency.
It's accurate, well made and at 11.5, resides in the goldilocks zone of ar applications. It's slightly heavier than the average 11.5, but you really, really want it that way.
No barrel issues, even under heavy course of fire. It's got about 3k rounds on it at this point, and I think it might shoot better than new.
I followed the included instructions on barrel break-in. After 30 + years of shooting and building AR's, I can't think of anything in the AR world that impresses me these days quite as much as the Noveske barrels.
While the accuracy is more than acceptable with range quality 55gr's, I've found the best results from 100-300 with 77gr pills.
