Well that is the night vision scope and the parade was pretty well lit.Note the shrouds for the optics.
With the new service rifle having a carbine, infantry, and DMR variant, there is a good chance that it may have a SAW variant at least being considered as well.
However, we also know that a dedicated LMG seemingly in 5.8mm is being developed (note the magazines in pictures 1 and 2)
This new LMG looks like it has a few things beneficial for the LMG role that a SAW variant of the new service rifle probably wouldn't have, namely the ability to be belt and magazine feed, and quick change barrel. It looks like it may also have a folding stock.
Would there be any rationale to develop a 5.8mm SAW variant of the new service rifle considering there seems to be a 5.8mm LMG in development as well?
In terms of differences, I imagine a SAW variant of the new service rifle would be perhaps a longer and heavier barrel, perhaps a different stock, and may be issued with a drum magazine (but also would operate with regular 30 round magazines), and maybe a different handguard too.
A SAW variant of the new service rifle would not be a true LMG as it wouldn't have the ability to change barrels or be belt fed, however I imagine it could be somewhat smaller and a little lighter than the new LMG we see being developed.... However the new LMG itself looks like it's designed to be somewhat lightweight and not too bulky (as opposed to say the M249) -- in fact looking at the new LMG with a 30 round mag in pic 2, its profile looks almost like a longer barrel assault rifle.
Could a SAW variant of the new service rifle complement a new LMG?

SAW or LMG both refer to a dedicated Light machine gun which is what those images clearly show. SAW of course references the M249 based off the FN Minimi.
The PLA in the QBB95 and CS/LR17 showed a “Squad Machine Gun” “Automatic Rifle” is another more appropriate term.
The first question is one of weight. Both M249 and the current PLA QJY88 are about 17 pounds empty weight. That’s not a “Light” anything. When you start adding in ammo this is not a weapon you wish to carry. This is likely at the heart of why the PLA issued the QBB95 at 8.6 pounds.
Well the US and others accepted the Minimi’s weight some have favored a lighter alternative. This is where LSW or IARs have come in. Objectively for a infantry small arm you want it under 12 pounds empty. Something closer to the Utilimax 100 in weight than the M249.

A patent document on the new assault rifle.
Gas regulator mechanism. Specifically a dual-chamber design to solve the gas port ablation problem. High-pressure gas from the barrel first enters (through the port) into an 'expansion' chamber to allow the pressure to dissipate, before the gas enters into the second chamber, which is the gas regulator itself.
Trigger assembly. Just a brief summary listing the IP categories the assembly belongs.
Patent for a magazine design that allows the operator to know – at a glance – that he is running out of rounds. Basically a colored indicator attached to the magazine spring that shows through a window to inform the operator that he has 5, 3, or 1 round left in the mag.
The 30-round mag.

Some speculate that the standard optic for the new assault rifle is based on this sight from Laserspeed out of Dandong, China. It apparently features both a tritium and fiber optic illumination. My technical Chinese on optics is non-existent, and since this is an image, I can't translate it easily. Could someone take a look and provide a translation?

More high-resolution images of the new assault rifle. Some of these have been shared before, but not in their original resolution.

not really a new idea. PMAG has that except larger.Patent for a magazine design that allows the operator to know – at a glance – that he is running out of rounds.

So it is a short stroke piston system.
Sounds a bit like the ACOG. It has a fiber optic “light pipe” and tritium. The Light pipe allows the radical illumination in day at night the tritium glows.Some speculate that the standard optic for the new assault rifle is based on this sight from Laserspeed out of Dandong, China.

Of course in high glare or light conditions this can be annoying so troops would tape over part of the tube.
