The RRA 350L0326 350 LEGEND CAR SS HALFHP UPPER from Rock River Arms delivers a complete, ready-to-assemble upper receiver assembly engineered for the emerging .350 Legend cartridge—a modern intermediate round designed for AR-15 platforms with reduced recoil and effective range for tactical, hunting, and training applications. This stainless steel construction upper is purpose-built for shooters seeking a caliber that bridges the gap between 5.56 NATO and .308 Winchester, offering shooters and agencies a lighter-recoiling alternative without sacrificing downrange performance. Rock River Arms' proven design heritage ensures reliability in professional and civilian tactical environments.

Built with stainless steel construction, the 350L0326 upper resists corrosion and extends service life in harsh field conditions—critical for law enforcement and military training programs. The half-length handguard (HALFHP) design provides ergonomic rail space for mounting tactical accessories while maintaining a balanced, lightweight profile ideal for CQB and vehicle operations. At 6.34 lbs, this upper assembly remains manageable for sustained tactical shooting, and the 16-inch carbine-length gas system ensures consistent cycling across a variety of ammunition loads. The precision-machined receiver and bolt carrier group deliver the tight tolerances demanded by professionals who depend on their rifle when it matters most.

Law enforcement agencies, military units, and civilian tactical shooters benefit from this upper's versatility and the growing ammunition availability for .350 Legend. Installation requires a compatible .350 Legend lower receiver and standard AR-15 tools; the upper's modular design integrates seamlessly with any mil-spec lower and accepts standard AR optics mounts and handguard systems. Trainers and precision shooters appreciate the .350 Legend's flat trajectory and manageable recoil for developing fundamental marksmanship without the wear of full-power rifle rounds. Whether for duty carry, training courses, or dedicated hunting platforms, the RRA 350L0326 upper bridges modern tactical demands and practical performance for sale today.
