The HM Defense HM50 Max in FDE (brand part no. HM50MAX50BMGFDE) is an American-made .50 BMG bolt-action rifle built around a 29.25-inch fluted barrel. HM Defense machines the upper receiver from 7075-T6 billet aluminum and the lower from aircraft-grade aluminum, and pairs them with a 14-inch free-floated Picatinny rail with an integral ARCA section and bipod mount. The barrel is match grade and button rifled, with a 1:15 twist, and it is threaded at the muzzle. The HM50 Max also has a profiled, lighter-weight action. It is built for long-range shooters who want a serious .50 BMG platform.
