I picked up a new Marlin 336C last night. I did a lot of research and thought, for sure, this would be what I wanted. While I was cleaning it today the firing pin looked a little wobbly, I pulled on it and the front firing pin, rear firing pin, and firing pin spring came out. After looking into it I realized it is missing the firing pin retaining pin. It's a cheap part and seems super easy to replace but I have to admit I'm a bit frustrated. It just seems like that should have been caught before it was shipped. I also tried cycling a couple rounds through it a few times. More than once it would not extract a round. I'm wondering if the parts list is going to grow. Now I have to wait for Monday to call Marlin and hope they send the part out or throw the pin in with my next Midway order. Maybe it was just a slip up at the factory but the situation is really lowering my opinion of my new gun. Bad timing too because I was just getting to know her. haha.
