COLT BOLT REPAIR KIT M4/AR15

Description

Bolt components are among the highest-wear parts in an AR-platform rifle, and having the right replacements on hand before a part fails is simply good practice. This factory Colt Bolt Repair Kit covers the critical small parts inside the bolt itself—the extractor, ejector, bolt rings, extractor spring assembly, extractor pin, ejector spring pin, and firing pin retaining pin—giving you everything needed to bring a worn or damaged bolt back to full function without sourcing individual components from multiple suppliers.

Because these parts come directly from Colt’s Manufacturing, they are made to the same specifications as the components originally installed in Colt M4 and AR-15 rifles. The extractor in particular is CAGE-code marked and dimensioned to Colt’s own tolerances, including the extractor spring pocket and spring wire diameter, so fit and function match what the bolt was designed around rather than requiring any trial-and-error fitting. That matters most when you need a repair to go smoothly under time pressure rather than on a workbench with unlimited patience.

The kit is appropriate for any AR-15 or M4 pattern rifle running a standard bolt carrier group. Whether you’re maintaining a dedicated range rifle or keeping a working carbine in top condition, stocking this kit means a cracked extractor or a worn ejector does not have to end a range session or a field trip. These are consumable parts by nature; replacing them proactively on a high-round-count bolt is straightforward preventive maintenance.
