WMD Guns’ proprietary NiB-X® coating delivers a finish that sheds carbon buildup, measures 40% harder than hard chrome, and provides exceptional lubricity to keep your AR-10 platform operating smoothly through demanding conditions. NiB-X® has proven its durability through a 30,000-round torture test without a single flake, chip, or thinning, and is backed by a lifetime guarantee against coating failure.
This .308 bolt carrier group features a 9310 steel alloy bolt and a carrier body machined from 8620 steel, with the gas key staked correctly for long-term durability. DPMS-compatible and built from top-tier components that have undergone all recommended treatments for longevity and reliable function, all bolts receive magnetic particle inspection and shot peening to ensure quality. The cam pin is completely coated with NiB-X® for lubricity and ease of operation.
Engineered without a hammer, this bolt carrier group presents an exceptionally slick surface that minimizes the need for additional lubrication while enabling fast and easy cleaning. The BCG components are coated and polished to reduce fouling adherence, making it ideal for shooters who prioritize maintenance speed and reliability in harsh, carbon-heavy environments.
