The FailZero AR-10 Bolt Carrier Group, No Hammer, Black (FailZero part no. FZ-AR10-NH-BLACK) is a fully assembled BCG built to drop into most mil-spec AR-10 pattern upper receivers. FailZero treats the critical wear surfaces with its EXO Nickel Boron coating, giving the group permanent dry lubricity along with a real bump in wear and corrosion resistance over a standard phosphate-finished carrier, while a black topcoat on the carrier keeps the look uniform with the rest of a black rifle build. This is the No Hammer version, so it’s meant for builders who already have a hammer on hand or are running a drop-in trigger group that supplies its own.

Key Specifications

• Ships fully assembled and drop-in ready for most mil-spec AR-10 pattern upper receivers.
• Critical parts are treated with EXO Nickel Boron coating for permanent dry lubricity that never wears off like a spray lube.
• The same EXO Nickel Boron treatment boosts wear resistance and corrosion resistance over a standard phosphate finish.
• A black topcoat is applied to the carrier only, while the rest of the group keeps its nickel boron finish.
• Built as a No Hammer group, so it ships without a hammer and expects you to supply your own or run it with a drop-in trigger group.
