Factory AI barrel profiles

[dms416]

Are all short-action AI AE/AW/AT barrel profiles the same?

I used to have a spare 26" AW barrel, and I was under the impression that the 26" was a slightly lighter profile.

Answered my own question. There certainly appears to be some differences in the contour of the 24" and 26" barrels. Pics and measurements to follow
