The HM Defense HM50B2 Gen2 (brand part no. HM50B250BMGTU) is a semi-automatic .50 BMG rifle, the evolution of the original HM50B, lightened and strengthened in areas that matter for military and law enforcement use, finished here in Tungsten. Its machined adjustable stock, built in-house by HM, uses a steel through-bolted mounting system to join the stock to the lower receiver, and includes an adjustable comb, length of pull, and butt pad. The 29.25-inch button-rifled, threaded barrel pairs with a 14-inch Picatinny rail and an HM Target trigger for serious long-range capability. It suits precision shooters who want full .50 BMG power in a semi-automatic platform, complete with a removable monopod mount, one 10-round magazine, and a hard case with laser-cut foam.
