The FailZero .308 Win DPMS Pattern Bolt Carrier Group is a fully assembled, drop-in upgrade for AR10 rifles built on the DPMS platform. Built around FailZero's proprietary EXO Nickel Boron coating, this BCG is engineered to run cleaner, last longer, and resist wear and corrosion far better than standard mil-spec carriers—making it ideal for shooters who demand reliability whether you're running distance rounds at the range, hunting in harsh conditions, or putting rounds downrange in demanding environments.
The magic here is the coating. EXO Nickel Boron creates permanent dry lubricity, which means less friction during the firing cycle and less need for obsessive cleaning. The carrier arrives with a tactical black topcoat for a non-reflective finish, though you'll notice the bright Nickel Boron layer gradually show through on wear surfaces like ramps, rails, and carrier contact points—that's the coating doing its job and actually a sign the system is performing as intended. Non-wear areas (like the dust cover region) typically hold the black finish.
Every critical component in this BCG receives the EXO treatment: the bolt and extractor (.308 compatible), the carrier itself, extractor cam pin, carrier key, and firing pin. It's a complete, ready-to-function assembly—no additional fitting or parts swapping needed. If you're building or upgrading a DPMS-pattern AR10 and want to reduce maintenance headaches while gaining an edge in durability, this is a thoughtful choice.
| Brand | FailZero |
| Caliber | .308 Winchester |
| Platform | AR10 (DPMS Pattern) |
| Finish | Black with EXO Nickel Boron Coating |
| Configuration | Complete Bolt Carrier Group Assembly |
| Components Included | Bolt, Carrier, Extractor, Cam Pin, Carrier Key, Firing Pin |
Yes, if your AR10 is built on the DPMS pattern and uses a standard mil-spec upper receiver. The group is fully assembled and ready to drop in. If you're unsure about your platform, verify your upper is DPMS-compatible before ordering.
You're getting a complete, assembled bolt carrier group: the bolt, carrier, extractor, cam pin, carrier key, and firing pin. Everything you need is in one package—no additional parts required.
The carrier ships with a tactical black topcoat on the outside, but the EXO Nickel Boron coating underneath is what does the real work. Wear areas like ramps and rails will naturally expose the bright Nickel Boron as the BCG cycles, which is completely normal and actually shows the system working. Non-wear areas typically keep the black finish. This design gives you the corrosion resistance and low-friction benefits of Nickel Boron while maintaining a non-reflective exterior appearance.
EXO Nickel Boron creates permanent dry lubricity, which reduces friction throughout the firing cycle. This means smoother operation, less carbon buildup, and less frequent deep cleaning—all while resisting wear and corrosion better than standard mil-spec steel.
