If there was a physical connection between the gas block and the handguard then it wouldn't be free floated.If it's so then it won't be floating barrel design, right?
Likely the front handguard can be disassemble into 2 major piece - the polymer handguard and the metal frame.
Looking at the rifle from the frontal aspect however, I think the bolts that Terran empire was talking about are not connected to the gas block. In fact looking at the frontal aspect and side aspects of the handguard I don't think there are connections to the gas block, so it should be free floated.
The handguard IMO is a single piece handguard that is made up of two components; a polymer part that makes up most of it and a metal part at the front of the rifle that includes an internal sleeve (again, not in contact with the gas block) + front BUIS + possibly even the top rail of the handguard.
But I don't think the handguard is designed to be separated into the two components by users normally, the two bolts on either side of the front handguard look pretty low profile and secure.
It looks to me like the "two major pieces" of the handguard is for the production in factory, but in practice the handguard is one piece as part of disassembly/field strip.
