What I don't understand is why are we still somehow treating this as a "one or the other" thing when the Chinese GDP clearly supports spending enough to invest properly in each soldier, I don't get why we still have to act like something like a free float tube is some sort of luxury that's somehow too expensive to afford. This logic is also how they got to them having to use those awful boots instead of something better.
In context of the PLAGFs overall funding, they probably don't have as much money to work with as we think. If we think about the PLA at large, sure it is certainly greater but that comes down to service prioritization.
Something like free floated handguards are a bit of a luxury in that regard (cost of such handguards versus the polymer ones they have now), especially if they don't also intend to have a use case for FF HGs (they aren't going to issue anywhere near enough IR lasers and NODs to make them necessary as a standard fitout).
This isn't to say that PLAGF procurement sensibility for infantry is rated well.
For example, the PLAAF made a great call by making Y-20B a MRTT, and the PLAGFs procurement of ISR and fires (PHL-191) was a bit of a masterclass truth be told.
It's not a controversy to say PLAGF infantry procurement leaves a lot to be desired, but imo it is a bit of a controversy for people to focus on it so disproportionately.
The glamourization of highly specced infantry and operators in media and PR is somewhat to blame for this.
There should perhaps be more movies and video games about artillery loaders, meteorologists and fire direction centers.
