HM Defense HM50 B1 50 BMG 26.25" 10+1 Semi-Auto Rifle

The HM Defense HM50 B1 is a 50 BMG semi-automatic tactical rifle built for extreme-range and anti-materiel work. The action rides in a hardcoat-anodized aluminum receiver finished in matte Black Hardcoat Anodize, and the platform is anchored by a heavy-contour 26.25" match-grade threaded barrel with a 1:15" twist to stabilize heavy .50-caliber projectiles.

Feeding from a detachable box magazine, the HM50 B1 delivers a 10+1 capacity in a package measuring 53.75" overall and tipping the scales at 28.75 lbs - a stable, bench-friendly footprint that keeps follow-up shots at distance manageable. The chassis carries a Picatinny optics rail across the top of the receiver, a free-float M-LOK handguard for accessory mounting, and a forward Picatinny forend rail for a bipod, light, or laser.

Shooter interface is handled by a smooth target trigger and a black stock with adjustable cheekpiece and length of pull, allowing the rifle to be dialed in for prone work or braced over a pack. Shipped new from HM Defense as a complete, ready-to-configure long-range precision platform chambered in 50 BMG.
