Opposing positioned are a second gas ring scraper surface, a second bolt face scraper surface extending from a terminus of the second gas ring scraper surface, and a second bolt cylinder scraper surface extending from a terminus of the second bolt face scraper surface. The first gas ring scraper surface and the second gas ring scraper surface are spaced apart from each other at a distance that is less than a diameter of a cylindrical gas sealing ring holding section of the firearm bolt.
