Reminton 700 AAC-SD barrel diameter?

[TB2Blazer]

Trying to get a brake for my AAC-SD and I don't have a pair of calipers to measure my rifle and I have also searched but nothing exact. Does anyone know the diameter of the barrel at the end or know of a way to measure it without calipers? I'm trying to get a recessed/countersunk brake and need the exact diameter. Thanks.
