The WMD Beast was the world’s first AR10 rifle fully coated with their proprietary NiB-X nickel boron coating process. They designed this rifle to be unquestionably the most reliable, battle- and hunting-ready, low-maintenance AR10 platform on the market. Now, WMD’s Big Beast takes all the features that made its 5.56 predecessor a benchmark in the industry and enhanced it to .308/7.62×51.
