Bolt Extractors

The bolt extractor in a BCG is designed to grip the rim of a cartridge, allowing the bolt to extract the spent cartridge case from the chamber of the firearm after it has been fired. This component is essential for the reliable cycling of the firearm, as it facilitates the ejection of the spent casing and the chambering of a new round. The bolt extractor works under high stress and must be both precise in its engineering and durable to withstand the forces of firing and extraction.
