Yeah, but in the 1950s, the Army was looking for a lightweight rifle and machine gun.

The FAL weighs as much as the M1, and the MAG is almost as heavy as the M1919A6.

Sure, the FAL and MAG were better than the M14 and M60 in some respects, but how did Springfield "screw us out" of them?

As for the AR-10, certainly it was basically a much better design than both M14 and FAL, but ArmaLite screwed itself with that.

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.

Steyr ACR - Advanced Combar Rifle - Modern Firearms

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

Reviewing last cutout video it seems to be clear. Thanks as always, Emeric

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?
