The Rock River Arms All Terrain Hunter 450 Bushmaster with 16" stainless steel barrel is a semi-automatic rifle engineered for medium to large game hunting and specialized tactical applications. Built on the proven AR platform, this .450 Bushmaster rifle combines the power necessary for ethical hunting with the ergonomic familiarity that operators and serious shooters demand.
The 16-inch stainless steel barrel delivers consistent velocity and accuracy while maintaining a compact profile suitable for brush hunting and tactical environments. The carbine-length gas system keeps the action responsive and reduces felt recoil impulse—critical when precise follow-up shots matter. The RRA 2-stage Ultra Match trigger provides predictable break and minimal creep, essential for fieldwork where accuracy at distance is required. The 13-inch free-float handguard isolates barrel harmonics for consistent shot placement, while the RRA Operator muzzle brake manages the substantial recoil signature of the .450 Bushmaster cartridge. The 6-position tactical carbine stock and Hogue rubber grip ensure a proper sight picture and control across shooters of varying stature. Black anodized finish resists corrosion in variable weather conditions.
This rifle suits hunters pursuing elk, hog, and large deer at intermediate ranges, as well as those requiring a powerful semi-automatic platform for reserve or training roles. The 5-round magazine capacity meets most jurisdictional hunting regulations while the AR ergonomics allow quick magazine changes when needed. The .450 Bushmaster cartridge delivers superior energy and penetration compared to traditional intermediate rifle rounds, making ethical one-shot kills achievable on game up to 300 pounds at practical hunting distances.
Rock River Arms rifles are manufactured in Illinois and known for consistent quality control and component integration. The All Terrain Hunter line specifically balances professional-grade features with hunting-appropriate ergonomics—a design philosophy reflected in this .450 Bushmaster configuration.
