gatnerd said:So the Bundeswehr is essentially getting a lower cost HK416.
Perhaps just as importantly, they're getting a HK416 that doesn't have a H&K logo on the receiver. I think that there were some politics involved in this selection.

What is the funcion of the lever that I marked on the photo? I believe that is some kind of foregrip retainer, but I would like to be sure

Yes its a clamp for a toolless handguard fixation. But i am not quite certain if its not mostly to avoid the HK patent on that. I think it must be quite a dance around all the patents that same folks have signed for 416 ,MPX, Car816,MP 556 etc
The patent density on Ar15 derivatives is getting ridiculous.
But from what we know now the MK556 was supposedly tested slightly better in tests than HK but more importantly was 52mio Eur cheaper, although that 52mio saving is also down due to some creative accounting on how much longer rifles could last because of the replaceable cam thingy.
Heckler patents and Haenel

Great info, thank you.
Is there any indication of the barrel steel / barrel life for the MK556 vs the H&K416?
Barrels being the major part that wears out first, it would seem that would have been a consideration for overall service life cost. And the 416 is known to have a very long barrel life.

There are other people who make barrels with that same steel though. HK definitely does not have a lock on that particular thing.

Do you know which other companies are using the same 'HK Steel?"
I seem to recall the steel was French?

I don't have that information offhand but iirc it's an aermet derivative steel and there's people doing high end CHF barrels using it here stateside.
I'll look at my notes

Aubert & Duval is the supplier. I can't share the exact alloy, but it's a ChroMoVan steel.

The typical German military barrel steel alloy is 32 CrMoV 12 10 and indeed I have seen batches from French steel mills.
