Big Horn Armory Rifles for Sale

Founded: 2008

HQ: United States

Big Horn Armory, Inc., based in the United States, is a boutique rifle maker founded in 2008 specifically to build a Browning-type lever action in .500 S&W Magnum, and rifles remain the company’s core focus. Its rifles are distinguished by big-bore performance from lever guns that marry 1886-style lines to 1892-inspired internals and modern 17-4PH stainless/CNC construction to handle .500 S&W pressures, plus an AR-platform option built around the proprietary .500 Auto Max.
