The weight of a water bottle would be well within the elastic limit of a steel gun barrel, the vibrations travelling across the barrel when the weapon is fired would contribute much more stress

They are confident with their quality. Who knows for how long the qbz19 can be sturdy
Don't worry, the weight of the kettle is not enough to deform the barrel.
One issue I've noted with the QBU-191's handguard is that on the six o'clock position there is actually no MLOK spaces for attachment of rail pieces, but instead it has cooling vent spaces of the same kind they have at the four 45 degree positions of the handguard.
That means they aren't able to mount any attachments further back than the integrated six o'clock pic rail that already exists.
For example in this setup, the vertical foregrip could have been placed a bit more backwards by an inch or so for length of pull, or alternatively by having a VFG in addition to a bipod at the front of the handguard.
Of course it isn't a huge issue, because it is primarily a DMR/HBAR, so the lack of six o'clock rail estate isn't a massive issue.
But it's still a bit of an odd design decision.
Would be nice if you could post the video without having others to do it.
