AR-15/M4 – Field Repair Kit – Small Parts Kit – Black
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
This Colt’s Manufacturing Field Repair Kit is a compact AR-15/M4 small-parts kit built for repairs, maintenance, and keeping common replacement parts on hand. It includes a broad spread of springs, pins, detents, bolt catch parts, buffer retainer parts, firing pin parts, and takedown hardware.
This is the kind of kit that saves a range day, a build night, or an armorer bench from being stopped by one tiny part with a bad attitude.
Fitment
- Fits AR-15/M4 pattern rifles.
- Built for common small-parts repair and replacement.

What it does
This kit provides common AR-15/M4 small replacement parts so worn, damaged, or lost parts do not stop the rifle from functioning or keep a build stuck on the bench.
Why it’s worth it
For AR-15/M4 maintenance, spare parts are not glamorous—but they matter. This kit keeps practical replacement parts together in one package, backed by the Colt name and useful for serious rifle upkeep.
