Rem 700 sps tactical AND sps tactical aac-sd barrel diameter

[3base]

Hi all,
I'm looking at both, both 20", 1-12 compared to 1-10, they both state heavy barrel,
but I've never seen both in the flesh & was wondering if any one can tell me if both the
Rem 700 sps tactical AND sps tactical aac-sd have the same barrel diameter or are they different?
Is one thicker that the other or are they different ?
Sorry I just can't tell by looking at pics & can't find any specs on the rem site.

Thanks !

They're indentical profile. Remington only uses 4 different contours to my knowledge. Remington varmint/Sendero/heavy, sporter, mountain, and magnum sporter.
