Allows for a long bolt travel and use the recoil-absorbing mecanism of the 75 mm Mle1897 field gun?

Well, since semi-auto firing is now the "only" firing mode used during training (full-auto is allowed in emergency case), we had no requirements for full-auto dispersion / rate of fire.
It's even more embarrassing when someone accidentally discharge a burst from his HK416 F in the floor of a truck, claiming that the gun was in the "safe" position, when the selector was actually in "full-auto". During 6 months, this guy was putting his gun on "full auto" thinking it was the "safe" position, then goes to "semi" to fire and bring it back to "full auto" when not firing.
Excellent trigger discipline, but the training was slightly deficient...

like in the GD LWMMG?

Adjust the shoulder angles on the locking piece for one. Shallower angles mean more delay which should mean lower cyclic rate.

Thank you, that is a very pragmatic approach without being distracted by emergency cases.

Also it strikes me that one way of making the ammunition more compact is CTA. What do ye think? Chances will be better if NGSW ends up CTA of course

CT cartridges are shorter, but also fatter. This will reduce magazine capacity.
