Got an email from them last night about their current sale, and they had the complete upper for $309.00. I didn't check to see all of the specs, so I don't know what the barrel twist is, or exactly what bolt/carrier it is, but it's an M4 profile complete upper. Wish I had the extra coin. I'd get one just for my sheetmetal lower project. Any rate, I thought this might help someone out.
