they can be hit or miss on quality and reliability. In truth , they are a copy of the marlin model 60 action; but I do like the synthetic stock, and I also like the fully adjustable rear site on them. And since they are only 100 bucks, you may want to think of it as a throw away, if it does not work well.
Or skip the above, and get a marlin mod 60, with a sythetic stock,
and get a super accurate rifle, that you can beat up, and is of course,
the origional. You can usually go to pawn shops, or gunshops , and find tons of marlins used, for under 100 bucks, and if they are not marked under 100 bucks, you haggle to get the price down. Just take along someone with you, to the pawn shop, who knows how they operate; if they sell you a bad/non working one, it is your problem not theirs. At a gunshop, the used rifles have to be tested working good , by their gunsmith, so the ones at the gunshops should be in working order...
