KAK Industry AR-15/M16 Carrier Completion Kit - Chrome

The KAK Industry Carrier Completion Kit is the small-parts set that finishes off or refreshes a mil-spec AR-15 or M16 bolt carrier group. This Chrome version (MO-304-1010-003) bundles the firing pin, cam pin, and retaining pin - the three internal components most commonly replaced during a BCG rebuild.

The cam pin is machined from 4140 steel, Swiss turned and heat treated, then finished in Hard Chrome for smooth tracking inside the carrier and upper receiver. The mil-spec firing pin and mil-spec retaining pin round out the kit, and all three components are sized to standard dimensions for drop-in fit on any AR-15/M16 style carrier.

Whether you are assembling a new BCG from a stripped carrier or refreshing high-round-count internals, this kit provides a cost-effective, purpose-built replacement set. Installation requires only standard armorer's tools and follows the standard AR-15/M16 carrier assembly sequence.
