I just bought a new 336C from a private party and shot it for the first time yesterday. Only incident at the range was the front sight hood popping off and hitting me in the head. Other than that I enjoyed shooting my first lever action. But after taking apart to clean, I noticed some abnormalities on the bolt... Thoughts?
Can't imagine how shooting would cause that; looks like bad machining. I don't think that it will affect the performance.

Welcome to MarlinOwners Nooner! As to your bolt, take a gander at two of mine I just pulled. The left one is off the 1994 Marlin .444 and the right from a 2001 336W 30-30. I find it interesting that they are cut opposite each other yet function without problem. Maybe one of the former employees we have as members here can shed a little light on this. I wouldn't be concerned at this point. Mr fixit

Little rough blank not quite full in that area. If you have a Dremel very carefully polish the rough outer edges where it might contact the action.

Right on with the polishing
If you want a smooth action you need a smooth bolt.I have only seen a couple worse than yours.Swany said it all.

The sides of that slot only matter as long as the lever fits thru. The important surfaces are the front & back. My 1955 is all beat up like maybe the lever was bent at one time & not finding its way home, then someone bent it the other way too far and dinged up the other side of the slot. When I got it the barrel was shot, we sent it to Marlin, they rebarelled it & replaced everything in need of replacing and left that bolt in it. I wouldn't sweat it too much.

Thank you all for the informative responses!
Like Leverdude said, no worries. The lever just slips inside of that slot and does not work against the sides, it only presses on the front and back.
I noticed the same exact thing on my 336ss. i hqve not shot it yet but noticed the rough machining on the bolt. I initially wanted to return it but after some research and reading this post, I will probably just try to polish it a bit for a little smoother action.IMAG0363.jpg
