Need help identifying AR Barrel?

[Justshootok]

I have a heavy barrel 1x9 twist, stamped M1S. I am trying to determine manufacture. Also how can you tell a WYLDE chamber from a 5.56 mil-spec chamber? Thanks

Make a cast of the chamber and compare the specs to reamer prints.

Only way to know for sure.

I am fairly sure Model 1/ Shaw uses 5.56 spec not Wylde.
