The Fail Zero AR15 EXO-Treated Bolt Carrier Group is precision machined to fit your AR15 and function flawlessly, but this bolt carrier group (BCG) has something more.
The Fail Zero Nickel Boron BCG is treated with EXO Technology, a metal coating that protects the parts against corrosion and wear typically sustained by firearm components. It even makes the parts less susceptible to carbon fouling, which means you won't have to spend ages scrubbing away at this bolt carrier group to get it clean. The EXO coating imparts a permanent lubricant quality to the metal, eliminating the need to keep a layer of oil on the parts.
Finally, the nickel boron coating is hard enough to withstand heavy use without ever flaking or rubbing off. The bolt, carrier, hammer, extractor, cam pin, carrier key, and firing pin have all been coated with EXO Technology to make the toughest BCG around.
