Rpk:
I'm probably off base here, but will comment, just in case. If it's actually an RPK for which you're looking, I can't help you much. The Romanian "sniper rifle," of which too many of our troops over there in the sandbox are seeing too many of the wrong end of, is actually a "PSL" (and I don't know the
Romanian translation off the top of my head) and is commonly not only known as, but even incorrectly marked as the Dragonov. It is not a Draganov, but is closely designed after the Russian RPK, and is originally chamber in 7.62x54r, and most recently in .308, as well.
