Why Choose Nickel Boron for Your 6.5 Grendel BCG?
Traditional phosphate finishes require lubrication and frequent maintenance. Fail Zero’s NiB coating changes the game:
| Feature | Nickel Boron (Fail Zero) | Traditional Phosphate |
|---|---|---|
| Lubrication | Self-lubricating | Requires oil |
| Clean-up | Wipes clean | Requires scrubbing |
| Durability | Excellent | Moderate |
| Performance | Smooth cycling | Standard |
Shoot more, clean less — EXO Nickel Boron technology drastically reduces fouling buildup and enhances performance in high-round-count sessions.
