US12287165 - Extractor for an autoloading firearm

The patent describes an extractor for autoloading firearms featuring a body with a knuckle that includes an elongated pin opening, allowing for improved movement during the bolt’s rearward action. This design prevents the extractor from pivoting about the pin, enhancing the reliability of the extraction process.
