The Patriot Ordnance Factory Minuteman Complete Upper in 5.56x45mm NATO features a 16.50" black nitride barrel crafted from 4150 Chrome Moly Vanadium steel and paired with an aluminum Patriot Brown receiver, delivering rugged durability and a refined, low-profile appearance. The 14.50" M-LOK handguard provides ample accessory mounting space while maintaining a slim, balanced profile suitable for both precise mid-range shooting and dynamic field use. A Lo Pro direct-impingement gas block configured for a mid-length gas system contributes to smoother recoil impulse and enhanced reliability across varied ammunition types, with the rifle-ready configuration permitting optic installation to meet custom aiming preferences. This upper is designed for versatility, offering an optic-ready setup without integrated sights, enabling shooters to tailor optics to their preferred thresholds for accuracy and speed. The combination of a generous-length barrel, durable black nitride finish, and Patriot Brown components ensures a consistent, corrosion-resistant surface that stands up to rigorous field conditions and repeated engagements. Ideal for enthusiasts seeking a complete, ready-to-build upper that balances control, reliability, and modular capability for versatile 5.56 NATO applications.
