My latest GG bought in 2003 (late pre-Remlin) or so barely cycled. Had to force the first round in and the next round would actually come in under the carrier, jamming it up completely (that is the "Marlin Jam" I've come to understand - I didn't have internet access where I lived then to research it) - not a great scenario if a grizzly bear were coming at me.
I took it upon myself to polish & tweak it (I was a looonnnggg way from any service center or the store I bought it at that point), got it functional & since then I've tuned it to a point that it works flawlessly and I love it.
But paying new rifle prices for a DIY project was not what I had in mind when I bought it. I really hope they've straightened themselves out and that Marlin isn't just another loss leader for Remington.
