Quoted:
An off the wall guess is that the version for Europe is so called and probably stamped .308 instead of 7.62 nato because some European countries don't allow their citizens to own weapons chambered in a military caliber and that's a easy loophole I'd imagine.
It's quite simple. Germany and the most of the European states too are members of the C.I.P. agreement community. And the civilian name of a 7,62 mm x 51, (you would write it 7.62 NATO I think), following this agreement, is .308 Win.
I would say it's a good idea of the HK marketing that they rename their 416/417s. M

ifle223 (Rem) and MR308 (Win) makes them really civil = non evil...
Look, even our surplus ammo must be C.I.P.ed = proofed a second time and, that is really crazy I think, ink stamped with the civilian name of the cartridge on each case.
But you live on the happy side of the big pond. You can buy a MR762. It's a emotional sales argument I think. Sounds tacticool.
