Will the AK-12 be produced in 6.5 Grendel? It certainly seems that way, based on this graphic at RIA.ru. It’s possible their information comes from Wikipedia, the English version of which cites a broken link (Russian Wikipedia makes the same claim, with no citation at all), but it’s also possible the information comes from an official source.
Also interesting is the weight of the AK-12, a quite reasonable 3.2 kg (about 7lbs). Previously, I had been concerned that the “tactical” features of the AK-12 would bring with them excessive weight, but it seems like this might not be the case.
Wolf began production of steel-cased 6.5 Grendel ammunition not too long ago, so a 6.5mm AK-12 certainly wouldn’t go hungry.
