KAK Industry AR-15 Carrier Completion Kit - Phosphate Cam Pin, Firing Pin & Retaining Pin

The KAK Industry AR-15 Carrier Completion Kit bundles the three small but critical components you need to finish out a mil-spec bolt carrier group: a phosphate-finish cam pin, a firing pin, and the matching firing pin retaining pin. This is the "PHOS" version, which uses a phosphate-plated cam pin to match traditional mil-spec BCG finishes.

The cam pin is Swiss-turned from 4140 steel, heat treated, and finished in phosphate to mil-spec dimensions for the AR-15, M16, and 5.56 BCG. The firing pin is precision ground from 8740 steel, heat treated, and hard chrome plated for dependable ignition. The included retaining pin locks the firing pin into the carrier and is ready for staking.

Designed as a drop-in completion kit for anyone assembling or rebuilding an AR-15 or M16 bolt carrier group, these components are built to standard mil-spec tolerances so they install in any mil-spec or compatible aftermarket BCG without extra fitting work.
