The FailZero EXO Coated Nickel Finish AR-15 BCG with Hammer is a fully assembled bolt carrier group built to run clean and reliable in your AR platform rifle. Unlike standard phosphate or chrome-lined carriers, the EXO nickel boron coating on critical surfaces eliminates the need for constant lubrication—a real advantage whether you're logging rounds downrange at the range, hunting in variable conditions, or maintaining your rifle in the field. Because it arrives fully assembled and drop-ready for most mil-spec AR-15 upper receivers, you skip the gunsmithing and get straight to shooting.
The nickel boron treatment isn't just a marketing gimmick; it fundamentally changes how the BCG behaves under use. The coating creates a permanent dry-film lubricant that reduces friction between moving parts, meaning less wear over the long term and less carbon buildup that typically requires aggressive cleaning. That translates to easier maintenance and longer intervals between deep cleanings—especially valuable if you run suppressed or shoot corrosive ammunition where traditional finishes can degrade faster.
Corrosion resistance is baked into the EXO coating, so your BCG holds up better in humid or wet environments without the extra babying that bare steel demands. This is the kind of upgrade that pays dividends across thousands of rounds, whether you're a competition shooter, a serious hunter, or someone who simply values a rifle that functions reliably with less fuss.

The FailZero EXO BCG is designed for most mil-spec AR-15 upper receivers. If your upper is mil-spec, it should drop in ready to go.
The EXO coating creates a permanent dry lubricant on the carrier's moving surfaces, which means you need less oil to keep it running smoothly. It also resists wear and corrosion better than traditional finishes, so your BCG stays cleaner and lasts longer with less maintenance.
It arrives fully assembled and ready to drop into your upper receiver. No additional assembly required.
Yes, this is a complete bolt carrier group assembly that includes the hammer.
