The SPIKE'S TACTICAL AR-15 5.56 NATO Complete Lightweight Nickel Boron BCG (ST5BG05) is the same lightweight BCG that Spikes Tactical uses in their builds and it is coated with the most durable finish on the market, nickel boron. Smoother and harder than hard chrome, it allows this bolt carrier group to be run almost lube free for thousands of rounds. It is being adapted by the US military and many government agencies as a standard for their BCGs.
