And it was fascinating because they had all these zany, really distinctive guns like four-barrelled shotguns and revolver-rifles.
Unfortunately they ran out of such weapons pretty quickly and the channel devolved into a lot of "this gun that looks and works just like every other AK-47 is interesting because it was made in Hungary, and most Hungarian AKs received an upgrade but this one didn't" which I personally felt was a bit of a snoozefest.
But if you're interested in seeing a great many very minor variants of mundane items, you might like gun history.
