Pairing the company’s M16 BCG (bolt carrier group) with its EXO Coated Trigger Group, the FailZero Elite Kit delivers both enhanced performance and great value for the cost-conscious AR-15 builder. Fully assembled and ready for drop-in installation, all critical parts on the BCG have been nickel-boron coated, as have the single-stage trigger’s components. This treatment increases resistance to wear and corrosion, reduces friction, limits the build up of carbon fouling, and provides dry lubricity. Black- and matte-finished BCGs are available for $10 more. Price: $200. Contact: FailZero; (866) 214-6926; failzero.com.
