There have been a few lately that have ended up with some shooters that I know. They are in fact performing quite well. They're strange-looking, light as a feather, fire-breathing brass slingers. Oh, and they're really loud. The triggers aren't so hot. They've been going for $400 in these parts.
I don't have much use for one myself, but otherwise they're pretty neat little guns. The lack of weight is kind of shocking when you pick one up. I've also been told more than once that loading the magazine to about 80% capacity (like 23-25 rounds, rather than 30) alleviates the primary feed issues. I guess some cases were getting beat up and dented a bit when people tried to squeeze 30rds in there. So maybe it should be called the PMR-24.
Good plinker, maybe varminter...can't really imagine any other practical use.
