Hi all I just got a new marlin 336c in 35rem. I took it to have a scope mounted on it and the screws in the receiver would not come out. I took it to a gunsmith and he could not get them out either. So sorry to say off to Marlin. Was not happy with it being new an all. But I'm sure marlin will get it stright. Has this happened to anyone else? Thanks for any replies.
