Brand new to lever guns and this forum. So I visited my LGS with a $100 gift certificate just looking around for what I could buy. I ran across a used Marlin 336c in 35 Remington for $250. It was immaculate, not a scratch on it! I had never owned a lever gun and knew nothing about them so I left the store to do a quick Google search on their value. Seemed like a good buy, so I took it. Since then I have seen that there may have been some problems with some Marlins after being bought out by Remington. The SN begins with a 92 and the barrel has a "JM" stamp. I have not fired it yet - should I be concerned? The only possible issue I noticed is that the rear sight leans a little to the left. Thoughts are welcome.
