I got my rainier arms ultra match .308 barrel today and it's supposed to be 20 inches long. It looks short to me. Where do I measure from to tell how long it is

From the bolt face when inside the extension

When locked inside the extension, and from there to the muzzle.  This is the ATF method of measuring barrel length, and all barrel makers use it for their measurements, though some may have a little "give or take" slop in there too.

Locked or not still the same length.

If it's locked, your rod/dowel can't push it farther back and give a false reading.
