>AK-12
Doing what goylil did long ago? Might be cheaper, but if they dump reliability and price because of the slight improvements in ergonomics AK kinda loses the point and nobody but Russian military will use it, because muh AK.tkb-517 had it all with a simpler system, lighter weight, better recoil management and ease of production, i'm fine with commies killing people, but why the fuck did these anal born mongoloids have to kill guns as well?
>PL-15
nothing extraordinary, it could be OK if it had the market, which it will not have because import regulations, local civvies never getting a handgun legally, army will be beating the crap out of Makarovs for a few more decades in the very least. Maybe FSB/spetsnaz will get some of them, but they will not go anywhere else in the near future. Police wouldn't care, it's not like they actually use their guns, they are more of a status symbol today.
Dunno about rpk.
There is also AM/AMB-17 rifles, there's not really much to it. better controls, lighter weight and style compared to VAL or VSK. 9x39mm is not a general purpose cartridge and Russian army would be the one who would care about solders' hear protection least, for sure.
