The WMD NIB-X CAM PIN 5.56 is a precision-engineered bolt carrier group component built to handle high-volume shooting. WMD Guns manufactures this cam pin to government M16 specifications, then applies their proprietary NiB-X nickel boron coating — a hard-anodized finish that outperforms standard chrome in durability and slickness. The result is a cam pin engineered for shooters who demand reliable, low-friction performance through thousands of rounds without accelerated wear.
The NiB-X coating does serious work. It's significantly harder than chrome and resists corrosion and abrasion in ways that matter when you're running suppressed, shooting in sandy conditions, or just pushing volume. Equally important: carbon fouling doesn't stick to the slick surface the way it does to conventional parts, so field stripping and maintenance take less time. For competitors running 3-gun or other high-round-count events, or dedicated range shooters who clean between sessions, this translates to less downtime and a gun that runs as clean as the coating keeps it.
Drop-in compatibility with standard 5.56 NATO AR-15 platforms makes installation straightforward—no fitting or modification needed. If you reload or shoot regularly, a quality cam pin that resists wear and fouling payoff over time.
| Caliber | 5.56 NATO |
| Finish | NiB-X Nickel Boron |
| Material | High-Grade Steel Alloy |
| Specification | Government M16 |
| Compatibility | AR-15 / 5.56 NATO |
Yes. It's manufactured to government M16 specifications, so it's compatible with all standard AR-15 and 5.56 NATO platforms. No fitting or modification required.
WMD's proprietary NiB-X coating is harder than chrome, resists corrosion and abrasion more effectively, and creates a slicker surface that minimizes carbon adhesion. This means faster cleaning and better performance under high-volume firing conditions.
It's purpose-built for high-round-count applications like 3-gun competition and regular range shooting. The low-friction, low-fouling design pays dividends when you're running significant volume.
