You've just gotten very opinionated about this. I see the essence of your argument as "the OICW didn't work out, the K-11 didn't work out, therefore it follows that the QTS-11 didn't work out.
The QTS-11 is supposed to weigh about 11 pounds loaded, with rangefinder and computer FCS, but without optics, roughly the same as the weight of the XM5 assault rifle.

As to shotgun rounds:
There's also claims of armor-piercing rounds (anti-vehicle). With that in mind, do you see my point about how the QTS-11, even if it fails, isn't in the same direction as the OICW?
In Chinese, it's a "strategic firearm", insofar as it drastically expands the capabilities of light infantry.
A lot of the information concerning the QTS-11, I think, is from Western sources who are half jealous and half skeptical of the QTS-11. For instance, somehow there's a claim that the
QTS-11 costs around 75,000 USD a piece. The original OICW was supposed to cost 10,000 USD, so how the hell did a Chinese clone / knock-off exceed that price? And our original numbers were 5 kg, but somewhere the weight rose to 14 lbs.
