Not sure what you mean.
It looks to me like using the Steyr ACR mechanism in a conventional rifle would not allow any reduction in weapon length.
And because of the downward ejection, I see no way to significantly reduce the overall length of the bullpup configuration.

If one applied the 85-100k pressures to , say, a .220 swift, what would the result be....could it reach NGSW energies?

Channeling 3600 J of KE in a .22" barrel would be interesting, for sure (75 gr VLD at >1200 m/s, seems it could be done at 90 kpsi in a 28" barrel, at least for one shot, maybe two).

And as we can see, the bolt carrier only travels far enough rearward for the rammer to align with the base of the next cartridge.

The tkb-022pm wasn't an AK prototype and no it's not a rising chamber Design.
It uses a falling breechblock and rammer design which is very ingenious.
Max actually has a YouTube video with a very accurate 3d model of it's internal workings.
The gun is pure genius in so many ways though not particularly practical or large scale producible.

I've always thought it was the solution to all the issues with a bullpup, but it is just a little too complex to be soldier proof. I imagine now it could be made cost effectively with CNCs and investment casting but even so that would be the only issue in it's way - beyond the unnatural bias against bullpups.

I'm curious how you reached that conclusion. Have you handled or fired one? Because it looks to me like the TKB-022 has most of the usual bullpup issues (e.g., poor balance and handling, excessive length of pull, etc.) and more.
With the extreme rearward location of the magazine, weapon handling and mag changes while wearing body armor and load bearing gear seem likely to be problematical.

So moved the controls back and add a 20 cm telescoping butt. all the issues with a bullpup solved.
