HM Defense HM50B2 GEN2 | .50 BMG | 29.25″ Barrel

The HM Defense HM50B2 GEN2 is a purpose-built .50 BMG semi-automatic rifle engineered for sustained long-range precision work. It combines a button-rifled, match-grade threaded barrel with an aluminum receiver and a machined HM adjustable stock to control the large .50 caliber platform. The rifle ships with a removable monopod mount, a 10-round magazine and a hard case with laser-cut foam. For optics, consider a Vortex Viper PST Gen II 5-25×50, which provides the magnification and reticle options suitable for extended-range engagements and is commonly available under $1,000.

Applications for this rifle include long-range precision shooting and ballistic testing/competition where a stable, accurate .50 BMG platform is required.
