American Rifle Company 0.473'' RH Bolt Head And Extractor

The American Rifle Company 0.473'' RH Bolt Head and Extractor is a precision component designed for owners of ARC Nucleus 2.0 and Archimedes actions who want to convert their rifles to different calibers without a gunsmith. This right-hand bolt head works with Savage-style small-shank barrels, enabling quick caliber swaps that transform your ARC action into a true multi-platform rifle. Built from hardened steel and finished with a DLC coating, the bolt head resists wear and corrosion through heavy use and years of field conditions.

If you already own an ARC action and want to expand its versatility, this bolt head eliminates the need for expensive gunsmithing work. Swap your barrel, install this component, and you're ready to shoot a new caliber—ideal for hunters who work multiple game across seasons, long-range shooters exploring different rounds, or anyone building a caliber-flexible precision platform. The DLC treatment protects the steel against the harsh environment and repeated firing cycles that come with active shooting.

This is the bolt head only; make sure your existing ARC action (Nucleus 2.0 or Archimedes) and your barrel choice are compatible before ordering. Confirm the specific caliber requirement for your new barrel setup, as bolt head specifications must match your intended round.
