The WMD Guns Big Beast 7.62x51 18" 20rd Silver is a modern AR-10 style rifle built around WMD’s proven NiB-X nickel boron coating for smooth operation and easy maintenance. This Big Beast configuration brings the company’s flagship treatment to a .308/7.62x51 platform, pairing an 18" barrel with a DPMS-style barrel extension and a free-floated handguard for consistent accuracy and reliable performance.

Designed as a versatile .308 semi-automatic rifle, the Big Beast is well suited for range work, training, and hunting where shooters want the familiar AR ergonomics in a harder-hitting caliber. The included 20-round magazine offers ample capacity, while the NiB-X coated bolt carrier group and fire control group help keep the rifle running cleaner over extended shooting sessions. WMD’s focus on durable finishes and thoughtful component selection reflects the brand’s reputation for practical innovation in AR-platform rifles.
