Yes according to Bill it is a chrome lined Saber Defense barrel that he used on this AA upper. I guess I should have been more clear in how I stated that.
Any chance you know what the spec opening is for the carrier key? I did not put my calipers on the new key but you could see a bevel at the opening indicating a smaller hole for the gas tube to slide into. On the carred key that came from AA there was no bevel and the hole looked bigger. I will have to check the difference tomorrow.
