Colt's Manufacturing Bolt Repair Kit – M4/AR15

This Colt's Manufacturing bolt repair kit contains the essential small parts needed to rebuild or repair an AR-15 or M4 bolt assembly. Designed for shooters who perform their own maintenance, this kit provides OEM-quality components to restore function to a worn or damaged bolt. Common applications include replacing lost or broken parts during field stripping, addressing failures to extract or eject, or refurbishing surplus bolts.

All components are manufactured to Colt's specifications and feature the same finish and materials used in their factory bolts. Installation requires basic armorer knowledge and proper tools—this is a repair kit for the bolt itself, not a complete bolt assembly.
