Default Now that's a dirty extractor.

Finally pulled out the Sterling 302, and tried to figure out why it was FTE on most every round. A careful look revealed that the extractor hook was barely gripping the case rim.

Now, this little critter has some small parts and was always reluctant to remove the external extractor. It has the pivot pin with a spring on the back end.

Using some low viscosity lube/penatrating fluid I was able to work the extractor as I flushed the recesses. After about ten minutes and a couple of dirty rags, things started looking better. I was starting to see full motion of the extractor and a proper grip by the extractor.

The little critter is back to shooting everyshot and ejecting properly.
I should have done this several years ago. I feel bad for overlooking this.

22 LR are notoriously dirty and it seems my cleaning just packed in the crud.
Looks like I can avoid removing the extractor, if i just spend a little more time in the cleaning process.

Extractors are frequently ignored when it comes to cleaning. And they are one of the most important parts to the proper operation of any gun.

I too have a Sterling 302, and I simply love that little pistol! My extractor has been acting up as of late, and upon very close examination, I found that the rim of my CCI .22LR ammo is a little rounder than the rim of my Federals. The Federal .22LR ammo seems to have a more pronounced rim, and the Sterling extractor grabs it easily and ejects it reliably. I think I'll remove the extractor and touch it up a bit with a stone.

Yup! Great Little Guns.

I will share this link. I have purchased a part or two from him.

Default On extractors ...

Thanks for the link. I removed my extractor yesterday and touched up the hook with a 60-degree stone. The slot was full of crud just like you stated, and the spring was pretty gummed up as well. I removed a few machining burrs from the front corner of extractor slot with a small file, and lapped the top and bottom face of the extractor. The only difficulty I encountered was driving the 1/16-inch roll pin back in squarely with my clumsy hands, so I bent it a bit. Fortunately I had a bunch of new ones laying around, so I chucked one in a small 3-jaw chuck, spun it, and filed a very slight lead on one end to guide it into the hole. Worked like a charm, and cycled both Remington, Winchester, and CCI ammo.


Do you know if the parts from gun-parts.com site are new old-stock or are they used?

A few years back I fired about 7,000 rounds through my 10/22 without cleaning. It was an experiment that I did. That thing was filthy! I had to clean that gun for a long time to get it 100% clean.

MOST (not all) parts from Numrich (gunpartscorp.com) are used parts from organ donor guns. Some are old new stock.

I have found that 90% of al problems with .22's are fixed with a good deep cleaning.

If I'm not mistaken, I believe that's a different company altogether. The link provided by KG7IL takes you to Bob's Gun Parts. But I suspect you're right about these parts, too, being used.
