**The extractor spring that comes with this extractor is for Ruger 10/22 rifles. Please use the factory spring when installing in a Ruger Mark Series Pistols
If you're tired of having to stop shooting and clear jams in your Ruger 10/22 or the Mark Series pistols, well now you can. There is one main reason that shell doesn't want to come out of there, it's the factory Ruger 10/22 and Mark Series extractor. Factory extractor works fine for a while, but after time, fine wears out. If you install a Volquartsen 10/22 Exact Edge Extractor, your Ruger will once again run fine.
The factory Ruger 10/22 extractor is simply stamped out of metal, and it wears over time. It doesn't keep positive pressure against the shell case, and that is why it fails. However, when you upgrade to a Volquartsen 10/22 Exact Edge Extractor you get a far superior part. This thing is EDM wire cut to precise dimensions out of hardened A2 tool steel. You get a precision-made extractor that keeps exact pressure against the shell case. Quality, this is exactly why you get 100% reliability, and that's as good as it gets.
Have you ever watched the competition "race gun" shooters and wonder why they don't have to dig out shells? Of course, the guns they shoot didn't cost only a couple hundred bucks at a big box store. However, one big reason is that they don't run a stock Ruger 10/22 extractor. Now, I'm certainly not implying that simply putting in a Volquartsen 10/22 Exact Edge Extractor is going to magically turn you into a pro. What it will do is help your Ruger 10/22 eject shells more reliably. You get more time shooting with less aggravation, your Ruger will thank you.
