Product Description The Noveske N9 Recon Gen 4 Complete Upper is engineered for the discerning shooter who demands precision and reliability from their 9mm AR platform. At the heart of this assembly is a 16-inch 416R stainless steel barrel with a 1:12 twist rate, individually serialized and hand-polished at both the chamber and feed cone to ensure consistent feeding, minimize the risk of jams, and deliver outstanding accuracy with a wide variety of 9mm ammunition. The 4th Generation precision-machined billet 7075-T6 aluminum receiver is finished with hard coat Type 3 anodizing followed by armor black Cerakote ceramic coating, providing exceptional corrosion resistance and finish longevity. A diamond-like coated, full-auto compatible Noveske bolt carrier group with a Grade 8 American-made, properly staked gas key bolt and an M16-style extractor rounds out the internals for smooth, reliable cycling. The included Noveske marked Geissele Super Badass ambidextrous charging handle and the 4th Generation NSR-15 free-floating M-LOK handguard make this upper a complete, ready-to-run package compatible with both Colt and Glock-style magazines.
