I am familiar with the Russian markings, so I knew it was a Russian reciever. I didn't know if the carbines were re arsenaled by Hungary or something. But, all Russian markings are still there, and no Hungarian markings are present (crest, 02, etc.), except of course the CAI import marking. So I assume the "Hungarian" marking was simply a mistake. It was redone by someone, as the stock has a blonde hue to it and is in perfect shape (not even a scratch), all blue looks brand new, and the bore shines like a mirror. The only mod I've done is a Mojo Microclick rear sight and it is the only Nagant I've ever shot that will shoot MOA at 100 yds. It takes a cold barrel to do this, however, after its heated up groups open up to 1.5-2", which I still think is pretty impressive for an open sighted M44. Ammo was Czech light ball. Have not bought dies for the 7.62x54r over the years, military ammo was always cheap enough. With surplus prices around here hitting $6-$9 a box, I will be ordering dies soon, then we'll see what the little '44 can really do.
