Marlin 39AS Disassembly

[Happy]

My 39 is starting to misfire and I would like to take it apart and give it a heavy duty cleaning but not sure how to go about it. It is a take-down model but I bought it used so I have no owners manual. Thanks, Hap

#1. Take a proper sized screwdriver or a quarter and back out the takedown screw until the threads are clear of the left side of the receiver. The takedown screw will not come all the way out because it has internal shoulders on it.

#2. With the rifle held in front of you horizontally pull the hammer back to the safety step. With the barrel pointed to your left bump the buttstock with the heel of your hand right behind the receiver to force the stock and the receiver plate to the right. Then seperate the stock and the right portion of the receiver from the stock.


If you want to go any further than that let me know and I'll give you further information on how to break it down further. Hopefully this will fix the problem as it is just a dirty firing pin assembly. Hopefully it is not a broken or worn firing pin. The chamber could be dirty also.

Thanks Allen, it came apart like a champ. One more question. Is the firing pin suposed to slide back and forth freely or is it held by a small spring. My firing pin is loose. Hap

Yes the firing pin should float freely on top of the breech bolt.
