Douglas barrel Markings.
Recently found an older Douglas barrel I had never finished and stored umpteen yrs ago. The chamber face has the words "A Douglas Barrel" and
"Premium Quailty". Also has 2 "Star" symbols stamped. Does anyone know what the stars mean or was it merely the symbol Douglas used years ago? I haven't bought a Douglas in a while, but thought they stamped "X's" on them. Thanks. Last edited by xcalibor67; February 1, 2015 at 04:00 PM. Reason: photo |

I believe that means it is the second barrel made of a new mandrel. They marked them with stars up to the 5th one.

So basically, One would think barrels made with the newer tooling would be more precise? I thought it might have had something to do with Air Gauging.

The two stars are just part of the "Douglas Barrel - Premium Quality" stamp.
Standard marking. Font, size, and quality of the stamping has changed over the years (as well as additional markings like twist rate, chambering, etc), but that's a standard production stamp for an older premium grade barrel.

Douglas premium barrels used to be those that air gauged to some groove diameter tolerance/spec. Not a diameter spec but how much they varied. I don't know what their specs are today, but years ago when some were gauged at a .0002" spread but 30 caliber ones had groove diameters well over .309".
One keen on this could contact Douglas then ask them. |

The folks over at Douglas are very cool to talk with, I talked to them about my barrel and they were totally eager to answer any question I had and when time come they will get the nod again.
