WMD NIB-X Bolt Carrier Group 5.56 Black

WMD NIB-X Bolt Carrier Group

The WMD NIB-X bolt carrier group represents a significant advancement in AR platform reliability and ease of maintenance. Every component receives a proprietary NiB-X coating and precision polishing to minimize fouling adhesion—a critical advantage when running suppressed or short-barrel configurations where carbon buildup accelerates rapidly.

Performance & Durability

Proven Endurance: WMD subjected this BCG to over 30,000 rounds of Government protocol testing without coating degradation. The NiB-X finish is guaranteed for life against chipping, spalling, or flaking under normal use.

Reduced Maintenance: The polished, coated surfaces shed carbon and fouling more effectively than traditional phosphate finishes. This translates to easier cleaning and more reliable function in demanding conditions.

Ideal Applications

This bolt carrier group excels in:

• Suppressed rifle platforms
• Short-barrel configurations (SBR)
• High-volume shooting sessions
• Environments where frequent cleaning is impractical

Specifications

• Caliber: 5.56 NATO
