Does anyone know what the under-the-handguard profile of this barrel is?

I bought a standard A4 complete rifle. It is a HBAR.

What is the diameter of an HBAR?

I have no clue. I can't measure because I don't have it yet. But I was told it was a heavy barrel and not the govt. profile. Sorry.

Just like this picture from RRA's web site under "Barrel Assemblies and Barrel Parts"

Kinda hard to measure from a picture though.

All standard production RRA barrels are heavy under the handguards, even the M4(R4) lengths.
