Need some help figuring out what piece I need for my Marlin Model 60 tube feed .22. The action stopped working and when I pulled the trigger off there was a crumbled up piece of hard plastic. Looked like a chopped up walnut. Problem is that it is so damaged I don’t know what piece to look for. Anyone know what I need and where I could find it? Any help is much appreciated!!

That would be the buffer: https://zephyrsmarket.com/products/marlin-recoil-buffer

If correct, that's dam impressive. '60's/'70's plastics.

Okay, thanks a ton! I’ll order one. I just clean up the gun and shot it 4 times without the plastic piece and it functioned properly! I wonder if it is okay to shoot this way until this piece comes in.

I actually bought this gun new around 2008.

That's more plastic than a buffer usually but there is no other plastic like that in one. Too bad it's a JM Marlin because it's from when there's a reason they sold to Remington. Good news it's not hard to replace and is cheap. The bad news is it's not as easy as on a 10/22.

I’m due a new .22 but would like to keep this one working

If you are local I will fix it for you if you supply the parts.

Gas guzzler, I sure do appreciate the offer but I’m in Longview.

Mine did the same thing, it's an easy and cheap fix.

Google is your friend, for now.

Do not shoot it without the buffer.

Great YouTube videos on replacing the buffer. Can't believe one disintegrated buffer would make such a mess.

A lot of the old buffers did that without even shooting the gun. Marlin Camp 9 & 45, HK Model 4, and many others. Even the Buffer in a MP5A3 falls apart over time.

Old thread, but I just took my Marlin apart to see why the bolt would not retract and found the same thing.
I easily found a downloadable 3D printer file, ordered some filament and I'll make a couple tomorrow.

Only shoot normal velocity from the Mod 60. No stingers. Wrap the spring with a split soda straw & small scotch tape to prevent bending. They will outshoot a stock 10/22.

you might want to consider replacing the spring along with the buffer
