Always been wondering why the Bundeswehr has never considered , last round bolt hold open as a tactical option?

Does this thinking go back to the time , aimed fire from a bolt action could defeat the M1?

That is about the only missing feature from my roller lock HK's that I miss. It is obviously not a deal breaker for me... but I also don't use them as my primary MBR so I can overlook that rather easily.
 
Bolt velocity on a G3 is high, and would beat a bolt hold open to death. It would fail, and cause malfunctions.

Ive been contemplating your assertion that do to the extreme velocity and mass of the apparent design failure , the German engineers couldn't overcome this engineering feat efficiently?
Just wondering why many 308' s ,such as the FN fal, m1a , etc.... must be the piston allowing the mass to be sufficiently reduced .
Do you have actual bolt velocity of the Hk 91?
 
Put the bolt and carrier on a scale and there is your answer. Same question on the AK too.

This was covered in a class I took in 1966.

My FNC and Galil don’t have it, so I can’t complain that the HK91 doesn’t have it either.
 
I thought that it had to do with having to send the bolt home at very high velocity to get it to "lock up" in battery after changing mags. That's why the G41 version of the HK33 also had a forward assist (or silent bolt closure as HK called it), because it had a last round hold open. Roller delayed bolts on HK rifles have to be sent to battery with some considerable authority to get it suitably in battery. Or at least that's the explanation I got in a Forgotten Weapons video on the HK21 GPMG (some HK LMG/GPMGs and the PSG-1 also used a similar silent bolt closure/forward assist).
