I disassembled my Marlin lever action (I believe 336) 30-30 for cleaning and came upon this spring, on the bench, when I was finished. I don't recall it falling out of the weapon and I can't I.d. it looking at the illustrated part breakdown of the Marlin. Do any of you recognize the spring? This is a new firearm recently added to my collection so very unfamiliar with it. Thanks. Andy.
