Rosco 16" mid barrel - Rosco Manufacturing Bloodline 5.56 NATO Mid Length Barrel

The barrel is nice and looks well made. The dimple for the gas block screw made alignment easy. After putting a few hundred rounds through the barrel it has been reliable and I have had zero issues. I cannot speak to absolute accuracy yet as I have not had a chance to do some bench rest shooting with match ammo yet, but it seems to be good. The only odd thing is the spent brass have very light scratches along the case. Maybe the chamber is a little rough? The scratches appear even when a fresh round is chambered and extracted without firing. Whatever causes the scratches on the brass, it does not inhibit function and appears to be smoothing out as I put more rounds through it. My barrel is gassed correctly and ejects at 4 o'clock. Either way it's a great barrel for the price, reliable, and groups well when I do my part
