My Double Star/J&T Distributing barrel is supposedly manufactured by Shaw but there are no obvious markings to indicate the manufacturer. My DS/J&T barrel is a good shooting barrel which is over gassed (large gas port). This was my first 6.5 Grendel AR-15 I bought in 2010 and my barrel is chrome moly (CMV). I recently added a Rubber City Armory adjustable gas Key and finally fixed the gas issue.
