Got a marlin 60 the other day from a pawn shop, i believe its 1984, took it shooting for the first time today. too much fun. one jam in about the 70 rounds i fired. anyway, assuming it is that old i want to clean the essential parts of the gun before i go out with it again. what products do you guys recommend for cleaning and what parts should i clean specifically? Are there any parts i should check for integrity and consider replacing? i googled it but im at a point where i only trust my fellow members for the best advice. thanks!
