JMR, if you don't mind my asking, what makes you say that the ramline stocks are junk?
Because I bought a used a rifle with one on it years ago. It was thin, flimsey, noisy and left 1/8" gaps between stock and metal. If someone made a decent stock at a good price for a lever gun I'd buy it. I have no doubt the MPI stock is a good stock, but it is not worth the asking price to me.
Right now the wood stocks are about as good as it gets. I have seen a few guys "paint" lever gun stocks with the same stuff they use in the spray in bed liners to get a tough, weatherproof finish. I've seen photos of some guy in Alaska with a SS guide gun done that way. Unique and serviceable to say the least.
