The FailZero 6MM ARC bolt carrier group with no hammer is a nickel-boron coated carrier built for the increasingly popular 6MM ARC cartridge. Whether you're setting up a new 6MM ARC upper or replacing a worn bolt carrier, this no-hammer configuration gives you a reliable foundation for a modern sporting rifle. The nickel-boron finish—FailZero's signature coating—resists corrosion and fouling far better than standard phosphate, which means easier cleaning between range sessions and longer intervals between deep maintenance.
The no-hammer design streamlines your build by letting you choose your own hammer separately, giving you flexibility to match your trigger group preferences. This is especially useful if you're running a tuned match trigger or a specialized trigger system where hammer selection matters. The 6MM ARC-specific design ensures proper function with this newer, intermediate-power cartridge that slots between 5.56 NATO and .308 Winchester in capability and recoil.
If you're building or upgrading a 6MM ARC rifle for medium-range hunting, target shooting, or general duty, a quality bolt carrier is where reliability begins. FailZero's nickel-boron coating is trusted by shooters who demand corrosion resistance and easy maintenance without paying premium prices for exotic materials.
