The extractor broke on my Marlin .22 LR model 670 81TS. I have been looking online to replace the bolt, but I am not having any luck finding an exact match. Does anyone know of a bolt that will fit this Model? Much appreciated thank you.
Numrich is my go to for rare, or hard to find parts.
It looks like the Marlin 81TS has been through a number of design revisions. It would behoove you to reach out to Marlin customer service with your serial number, and possibly pictures, t to determine year of manufacture, and parts compatibility. If Marlin doesn't have the parts you need, Numrich is your second best bet.

There's an extractor on eBay if that's all that's broken.

As ItsanSKS said, the 81's went through 3-4 different bolts styles.
One source for an extractor or an entire bolt may be Jack First. You have to call them and try and talk them through what you need.
