could be a couple things......do you know how to completely disassemble ?

pretty simple.....with correct sized screw drivers......watch U Tube vids........

Magazine tube could be dirty/cruddy........a new follower may help...clean inside tube

With my Marlins.....I pull down & completely buff innards......on buffer wheel & blue compound

Go over to 'marlinowners.com' good advise there....here's links for ideas......

I like them ole Marlins...........
