0.588'' Right Hand Bolt Head And Extractor

The 0.588'' right hand bolt head and extractor is a precision-engineered component designed for shooters and armorers who demand reliable firearm function under demanding conditions. Built to exact military and law enforcement specifications, this bolt assembly part ensures consistent extraction and chambering performance in rifle platforms. Whether you're conducting maintenance on a service rifle, building a custom upper, or replacing a worn component, this right-hand bolt head addresses the critical need for extract reliability that separates functional firearms from unreliable ones.

The 0.588'' bolt head diameter specification is the standard dimension for direct-impingement and piston-driven rifle systems, ensuring compatibility with standard bolt carrier groups and upper receiver assemblies. The extractor design—hardened to resist wear and deformation—engages the cartridge rim with positive pressure, preventing failures to extract that compromise magazine-fed reliability. Right-hand configuration positions the extractor for clockwise bolt rotation, the industry standard for American-pattern rifles. This component is manufactured to close tolerances, guaranteeing proper fit within carrier assemblies and repeatable performance across thousands of firing cycles without drift or degradation.

Professional armorers, military small arms technicians, and serious rifle builders rely on this bolt head and extractor for upper receiver builds and complete firearm assembly. It is essential for anyone rebuilding a bolt carrier group, replacing a damaged extractor, or standardizing components across multiple rifle platforms. Installation requires proper assembly knowledge and typically involves carrier group disassembly; ensure you follow manufacturer guidance and use appropriate roll pin tools to secure the extractor. This component is the foundation of reliable extraction and directly impacts the dependability your rifle demands in the field or at the range.
