Looks like the QBU191 is getting some love also it's good to see someone going for comfort.
Placing the optic on the handguard like this is not a good idea. It won’t maintain proper accuracy as the handguard is much more susceptible to movement and bending than the actual upper receiver. I hope they figure this out soon.

Optic looks backwards? But yeah you're right.

That depends on the rail system. In this case the system looks to be an aluminum one. Which generally has more structure and rigidity.
It is unusual to see that far forward but not unheard of. Particularly in the concept from the late Col. Jeff Cooper who advocated for what he called a “Scout rifle”. Said scout rifle was to use a forward long eye relief scope the idea being that the shooter would have maximum peripheral vision. Which made sense in both hunting and in tactical situations. Both because you never know when another Apex predator might decide to pop up and make you the prey.

No it’s right. You can see the power ring in the rear. It’s an LPVO which makes sense for a scout or DMR.

It is well-known that you shouldn’t place optics on the handguard, no matter what it is made out of. Aluminum rails are actually quite susceptible to bending. Just read about USASOC’s adopt of the MK16 rail and what problems they faced.

Same can be said about mounting the optic partially on both the upper receiver and handguard, also known as “bridging.” You should avoid mounting aiming device on the handguard whenever possible.

That I think is more a matter of opinion than actual facts. The advantages for mounting forwards are increased peripheral vision and on a sight like we see you kinda balance the weapon better. The biggest disadvantage is actually cleaning under the rail will often cause you to Loose zero. Issues like bending and the like might happen no denial but the upper rail on most modern rifles is pretty durable. Besides soldiers mount Laser sights and other equipment on the guard regularly. Clip on night vision devices are also often mounted there.

The conventional over receiver mount has its advantages as well easier to line up on The mount on the receiver has less chances of losing zero. Yes the receiver is more structural so less risk of wet noodle.

Biggest problem with the assessment you are making my friend is this isn’t AR15. What is true for AR15 may not apply to QBZ191 and vis-à-vis. So when I see the soldier with his mount that far forward. Well first we know that isn’t the norm other photo show it in the conventional configuration. But it’s not necessary without reason or merit. AK rifle’s for example with aftermarket rails often mount forwards as the dust cover even with rails is as giggly as jello.
