Stan, I believe that you misspelled "nearly all" as "some."

I realized that Textron / HK rifle is needlessly extended backwards. As there isn't backward extraction, backwards movement only needs to reach the base of the fresh cartridge.
Just look at Steyr ACR. Before I could see the internals, I wondered (during the 80s and 90s) how the magazine was so close to the buttstock. And here you are.
Recovery spring can also work against recoil and thus it needs a sizeable working lenght. But it could be placed elsewhere and save some lenght to the weapon, even permitting an innovation as novel and groundbreaking as a folding stock

A lot of bolt travel equals less bolt velocity before hitting the buffer and less "felt recoil".

The soviet prototype AK used this too...i think it was called the TKB022...
am i rigt in thinking they both use the same rising chamber mechanism..
Also, any thoughts on that 'finned bearing surface' in terms of feasibility?
Seems like a way to get a .22 up to 762 nato energies - without a sabot

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).
