WMD brings the advanced performance of NiB-X® nickel boron and other performance coatings to one of the most critical components on your AR.

Our premium BCG is coated in our proprietary NiB-X® nickel boron coating and polished to a presentation-grade sheen, this top-quality BCG resists fouling, needs practically no lubrication, and can be cleaned with a quick wipe of a cloth. We offer a variety of calibers and other popular performance coated BCGs.

We’ve run thousands of rounds between cleanings without malfunctions. Military personnel have praised its performance in desert conditions (where heavy lube buildup could attract deadly dust and grime). You’ll find that it provides extraordinary reliability…while dramatically reducing the time you spend cleaning.
