I have one, 22/410 and like most of my guns I haven't shot it. It is very well made, tight to open, looks European. Much more substantial than the new savage 42 and a good price compared to existing o/u. I don't like the looks of the opening lever but it works just fine. It folds (sort of) not enough to make it really packable. I read somewhere that the hinge bolt was removed and replaced with a pin that could be removed to break it down for packing. The accuracy reviews I have read are pretty good for this type of gun. I think I got it from either Buds or Sportsmans guide. Sights seem decent, probably better than most.
I have the Little Badger; if the quality is the same, they aren't much. I was able to "file" the shelf to smooth it out so the barrel would completely latch by using an emrey board. The metal is as soft as pot metal, in my opinion.
I had one in .22 lr over .410. It was accurate enough. It did not fold completely in half. It was finicky about ammo. For some reason, the Aguila ammo would suffer light primer strikes and not fire. CCI worked well enough. For a "survival" firearm, it must be reliable with ammo. So I sold mine. (No problems with .410 shells.).
