What is NiB-X and why is it better?

NiB-X is WMD's proprietary nickel boron coating. It is harder than chrome, self-lubricating, and highly corrosion-resistant, making AR-15 components easier to clean and longer-lasting.

Is NiB-X good for suppressed AR-15 builds?

Yes. NiB-X coated BCGs resist carbon buildup and reduce fouling, which makes them ideal for suppressed or short-barreled rifles.

Are WMD BCGs compatible with all AR-15 rifles?

WMD BCGs are designed to fit standard mil-spec AR-15 platforms. Be sure to select the correct caliber (5.56 or .308) for your rifle.

Do WMD trigger kits come pre-assembled?

No. WMD trigger components typically come as part of a lower parts kit and require standard installation, but offer smoother performance thanks to the NiB-X coating.

Do I need special tools or lube for NiB-X parts?

No. NiB-X parts run clean with minimal lubrication and require no special tools for installation. They’re ideal for easy maintenance and long-term performance.

WMD Guns – NiB-X Coated BCGs, Triggers & AR-15 Parts

When it comes to durability, reliability, and clean-running performance, WMD Guns sets the standard.

Ideal for:

Bolt carrier groups that see heat and grime
Triggers where a smooth break makes all the difference
Lower parts kits that benefit from enhanced wear resistance
Complete AR-15 rifle kits with mission-ready dependability
