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.

If there was a physical connection between the gas block and the handguard then it wouldn't be free floated.

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.

Like M16, field strip does not include the disassembly of the front handguard, field strip typically is tool-less, so anything the involves a screwdriver won't be consider field strip.

With the new service rifle's handguard, I don't think it is meant to be separated into its separate components at the armoury either.

I suppose what I'm saying is that I think the handguard is meant to come out of the factory as "one piece" permanently, and that the only way in which it would be separated is if it was broken in which case it would either be replaced with a new handguard or have to be sent to an armoury or depot or something to be repaired.

I might be wrong, but the handguard looks like it is meant to be one distinct piece and not intended to be separated into its constituent two parts once out of the factory.

If that's the case, they'd have use stamp rivot bolt instead of allen key.

Naturally, over its service life the polymer parts will be more subject to wear and tear (thus shorter lifespan) than the metal parts, so it'd make sense to make it replaceable repair job at armour's level. They could easily have some stocks of replacement front handguard module for fast replacement, the armourers can then repair the damaged front handguard module by switching out the damaged piece and pop in new piece.

Is it an allen key bolt though?
In the highest quality pictures I've seen, the screwhead looks circular rather than the hexagonal shape of an allen key, though I admit even the highest quality pic we have so far is not definitive IMO.

If it is later confirmed to be an allen key then I would agree that the two pieces are likely intended to be separated and changed at probably the armourer level.

From the picture, I wonder if it is possible to put in a dust cover that opens up, since opening downward would block the charging handle. I mean they took in the time to design the charging handle to be on a separate opening.

STG44 had such a cover although the charging handle was on the opposite side of the receiver. So it’s possible. Would just need to open the cover before chambering a round. As the cover would likely be blocked by the hand using the charging handle.

Around 18:35 mark, a segment on the No. 208 Institute, which was responsible for the new assault rifle family.

Some screen captures.

It's from that report, there's about a second or 2 between the timestamp which the focus adjusted just enough to see the straight edges to indicace those are allen key...
