What profile is under the handguard on this M15A4 barreled flat top upper with the midlength handguard?

Medium profile - not quite gov't and not HBAR.  I had one installed on this upper:

I don't know, I don't own it anymore and I never measured it.  It had a gov't profile look to it, just a bit fatter, IIRC.

I had one as well... but don't anymore either.  It looked to be in the .700-ish area.  Not at all a government profile, but smaller diameter than the area immediately behind the gas block.
