Shaw AR-15 upper receiver assembly in 300 Hammer caliber. Features 16-inch heavy barrel stainless steel construction with 12-inch handguard for precision shooting.
This Shaw upper receiver represents a thoughtful approach to modern rifle building. The 300 Hammer cartridge offers a compelling middle ground for shooters seeking performance beyond standard intermediate cartridges without the complexity of magnum recoil.
The stainless steel barrel resists corrosion and maintains accuracy over extended shooting sessions. The heavy profile reduces harmonic vibration, promoting tighter groups. The 16-inch length balances velocity with handling—ideal for both range work and field applications.
This upper assembly is designed for shooters who understand that precision begins with quality components. Whether you're building your first AR or adding to an existing collection, Shaw's attention to manufacturing standards makes this a solid foundation for a reliable rifle.
This is an upper receiver assembly only. You'll need a compatible AR-15 lower receiver to complete the rifle.
