I took the action of my 22 marlin apart to put a new mag latch on. While I was working on it I told myself I would not mess with the trigger spring and end up loosing it like I have read on the forums. Well something happened and it exploded on me the spring shot out doing 100 miles per hour and another part to S**T I didn't want that to happen. I looked for over an hour with a mag light in my garage and some how found the spring and another part with the help of a parts picture I knew what I lost.I then put it back together the springs on the semi auto 22' are a bitch to put back they are very strong .Well to my surprise the rifle works very good now mag latch is nice and tight the mag does not fall out anymore.The trigger is a lot better to all that powder residue built up was the problem of it having a crappy trigger.This is the first time I had the action out and it was very dirty this marlin is 20 years old . I should have done this a long time ago.I took it out today and it was shooting great.
