Bolt Ejector Pin

AR-15 Bolt Ejector Pin

The AR-15 Bolt Ejector Pin secures the ejector and ejector spring within the bolt assembly. This solid cylindrical pin is manufactured from hardened steel and uses a press-fit installation method for retention within the bolt body.

Key Features

• Hardened steel construction
• Solid cylindrical pin design
• Standard steel or phosphate-style finish
• Press-fit installation into bolt body
• Retains ejector and ejector spring under tension
• Platform-specific compatibility

Perfect For

• Bolt assembly repairs and replacements
• Builders maintaining AR-15 bolt carrier groups
• Gunsmiths servicing ejector systems
• Replacement of worn or damaged ejector pins

Component Function

The ejector pin retains the ejector and ejector spring within the bolt assembly, allowing the ejector to function under spring tension during the extraction and ejection cycle. The pin fits into a machined hole in the bolt body through press-fit installation.

Material and Finish

Hardened steel construction provides resistance to wear during repeated cycling. The standard steel or phosphate-style finish offers corrosion resistance while maintaining dimensional stability for secure retention.

Compatibility Consideration

This ejector pin is designed for platform-specific bolt assemblies. Verify bolt type and dimensional requirements before installation to ensure proper fit and function.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws.
